Authors: Mishra Namita , Arora Divya , Kumar Madhav , Kaur Satinder , Kumar Parmod
Published: July 2024

Aim and objective

The present study was conducted to compare the efficacy and safety of dexmedetomidine and midazolam with propofol alone for sedation during awake fiberoptic nasotracheal intubation. The study was conducted on 40 patients of either sex aged between 18 and 60 years belonging to ASA I–II grade scheduled for elective surgery. The patients were randomly divided into two groups of 20 patients each. Group I patients received intravenous midazolam 0.02 mg/kg followed by dexmedetomidine 1 μg/kg bolus infusion over 10 min, and then an infusion of dexmedetomidine 0.1 μg/kg/h and titrated to 0.7 μg/kg/h to achieve an adequate level of sedation. Group II patients received intravenous propofol 6 mg/kg/h bolus over 10 min with an additional dose of 2.4 mg/kg/h as infusion until they were adequately sedated. Hemodynamic parameters, comfort scale values, and patient’s tolerance were assessed.

Patients and methods

Fiberoptic nasotracheal intubation was done in both groups of patients, and after securing the tube, general anesthesia was administered. Within 24 h of the surgical procedure, each patient was asked to assess their experience with awake fiberoptic intubation. The data were recorded in the proposed proforma, and the final result was analyzed statistically.

Results

During sedation during fibreoptic procedure (FOS) and ET insertion, pulse rate (P=0.0116), systolic blood pressure (P=0.30), diastolic blood pressure (P=0.326), oxygen saturation (P=0.53), total comfort score (TCS) (P=0.031), and patient tolerance (P=0.023) were observed and showed statistically significant values.

Conclusion

Dexmedetomidine and midazolam group had a lower baseline mean heart rate. Systolic and diastolic blood pressure responses measured at preoxygenation, fiberoscope insertion and endotracheal tube placement were not significantly different for both patient groups. The five-point fibreoptic intubation scores showed better patient tolerance in the dexmedetomidine and midazolam group of patients and better comfort score as compared with propofol, and patients were calmer in the dexmedetomidine group.
Electrical cardiometry assessment of cardiac output compared to echocardiography in septic shock patients
Authors: Mahrous Atef A. , Helmy Tamer A. , Nabil Ahmed M. , Ibrahim Nagy Rawan M.K.
Published: July 2024

Background

Cardiac output (CO) measurement is essential for guiding therapeutic decisions in critically ill patients. Electrical cardiometry (EC), which is based on thoracic electrical bioimpedance, can measure CO in a continuous and noninvasive way. The benefits of EC are continuous monitoring, low time consumption, portability, and user independence. Transthoracic echocardiography has been a noninvasive method to assess CO despite being noncontiguous and operator dependent.

Aim

This study aimed to compare EC and echocardiography (Echo) in measuring CO in septic shock patients and assess the reliability and accuracy of EC for noninvasive CO monitoring.

Patients and methods

Fifty adult patients were admitted to the Critical Care Medicine Department, diagnosed with septic shock according to the surviving sepsis campaign, and fulfilling the inclusion and exclusion criteria from January 2023 to October 2023, and they were subjected to EC, Echo, and ECG recording.

Results

There was a strong positive significant correlation between CO measurements by echo and EC (r=0.988, P<0.001), and there was a strong positive significant correlation between stroke volume (SV) measurements by echo and EC (r=0.999, P<0.001). Also, there was a strong positive significant correlation between SV and CO measured by both techniques (r=0.782, P<0.001) (r=0.790, P<0.001, respectively).

Conclusion

Compared to Echo, EC can be used as a continuous, noninvasive method for monitoring CO and SV, as it provides accurate and reliable measurements.
Intraperitoneal instillation versus port-site infiltration or subcostal transversus abdominis plane block for post-operative analgesia following laparoscopic cholecystectomy
Authors: D’Cunha Delma , Somayaji Ananth S.
Published: July 2024

Background

Although pain after laparoscopic surgery is less compared with open cholecystectomy, pain management in the first 24 to 72 h in the postoperative period is tricky and most patients complain of pain with cough, breathing and mobilization during the initial hours. The aim of this study was to evaluate the most efficacious route of analgesia in patients following laparoscopic cholecystectomy by comparing port-site wound infiltration, intraperitoneal infiltration and subcostal transversus abdominis plane block in providing post-operative analgesia following laparoscopic cholecystectomy.

Methods

This was an observational study performed on patients who underwent elective laparoscopic cholecystectomy at a tertiary care hospital in Mangalore. Group A received bupivacaine instilled in gallbladder fossa after removal of gall bladder before closure. Group B received Bupivacaine as an infiltration into the skin incision site (fascia, muscle, preperitoneal space) at each of the four port sites based on the length of the skin incision before closure. Group C received bupivacaine as subcostal transversus abdominis plane block under ultrasound guidance immediately postclosure. Collected data was entered in Microsoft Excel 2007 and analyzed using SPSS version 22.0 to find frequency, Mean and SD. Significance was assessed using Kruskal–Wallis test, χ
2 test and ANOVA for repeated measures.

Results

Hemodynamic parameters, i.e. the heart rate and mean arterial pressure were comparable at the end of 2 h and 4 h. At 6 and 8 h postoperatively however, visual analog scale was significantly better in group C compared with groups A and B. Time until the first analgesic request in group C was 359.35±45.55 min which was significantly lesser than the other two groups. Only three patients from group B had shoulder tip pain which was not seen in the other two groups.

Conclusion

Infiltration of bupivacaine at port sites is helpful in providing effective analgesia for upto 2 h post operatively whereas intraperitoneal instillation is both effective at meeting analgesic requirements as well as preventing shoulder tip pain. However, the substantial finding of our study is in providing further evidence to existing data that Subcostal transversus abdominis plane block can produce effective analgesia for laparoscopic cholecystectomy, effectively reduces analgesic requirement, and ensures faster recovery.
Stealing-like phenomenon with interscalene nerve block and its influence on the regional blood flow during shoulder arthroscopic surgery
Authors: Kamel Walid Y. , Khattab Yosra A. , Haggag Adham M.
Published: July 2024

Background

Hypotensive anesthesia during shoulder arthroscopy is mandatory. Hypotension in the supine or decubitus position is safe and effective for reducing blood losses and for maintaining a clear surgical field. However, in the beach chair position, major complications have been reported. The current study claims that the alignment of the vessel in these regions favor a stealing-like phenomenon associated with interscalene block. This phenomenon has a good impact on the surgical field.

Results

There was a significant change in the peak systolic velocity between the two populations with values of 57±5 in group I versus 90±12 in group G, with a clearer surgical field in group I than in group G. The need for the intraoperative adjuvant analgesics was higher in group G (29 patients) compared with group I (10 patients) as was the pain score at early postoperative intervals of 6 and 12 h.

Conclusion

The distribution of blood vessels in this region favors a stealing-like phenomenon may be because of the associated vasoplegic effect with the interscalene nerve block, yielding a favorable surgical field without deliberate hypotension.

Authors: El Derh Maha S. , Ewiss Hassan Bahaa E. D. , El Shaer Ahmed N. , Shady Mohamed A. A. , Saleh Mohamed
Published: July 2024

Background

In recent years there has been an increasing interest in the practice of regional anesthesia especially peripheral nerve blocks for surgical anesthesia and postoperative analgesia. Imaging guidance for nerve localization helps the promise of improving block success with fewer complications. Among the imaging modalities available nowadays, ultrasonography seems to be the most suitable for regional anesthesia. One the most significant advantage of ultrasound (US) technology is the availability to provide anatomic examination of the area of interest.

Aim

The aim of this study is to evaluate the additive effect of dexmedetomidine to levobupivacaine in femoral sciatic block in total knee replacement regarding the onset and duration of both sensory and motor blockade, postoperative analgesia requirements.

Patients and methods

After ethical approval, 60 patients aged 45–65 years old, with an American Society of Anesthesiologists (ASA) physical class I and II who underwent total knee replacement using combined femoral-sciatic nerve block, were included in this prospective, randomized, controlled, double-blinded study. Patients were randomly assigned to receive levobupivacaine alone (group B) or dexmedetomidine 100 µg added to levobupivacaine (group BD) [n=30 patients for each group] for combined femoral-sciatic nerve block.

Results

This study showed that the addition of dexmedetomidine 100 µg to levobupivacaine during ultrasound-guided combined femoral-sciatic nerve block for total knee replacement was associated with, −20% shorter onset times for sensory and motor block, −25% faster time for surgical readiness, and longer duration of sensory and motor block (+45% and +40%, respectively) and +50% longer duration of analgesia.

Conclusion

Addition of dexmedetomidine to levobupivacaine during combined femoral-sciatic nerve block for total knee replacement was associated with faster onset of sensory and motor block, decrease intraoperative and postoperative requirements of analgesia and longer duration of motor block than levobupvicaine alone.

Authors: Mansour Mostafa S. , Sedky Asmaa M. , Sultan Amany A.
Published: July 2024

Background and objective

Emergence agitation is a common phenomenon in children recovering from general anesthesia. An emergence agitation reaction increases the risk of injuring the surgical repair, the patient, and the caregivers. Thus, we aim to explore the efficacy of melatonin premedication on emergence agitation in children undergoing herniorrhaphy surgeries.

Patients and methods

A randomized prospective triple-blinded trial was conducted on 117 children with herniorrhaphy surgeries conducted at the Anesthesia, ICU, and Pain Management Department, Menoufia University hospitals from April 2022 to July 2023.

Results

Yale preoperative scale at the start did not significantly differ among the studied groups (P>0.05). However, the Yale preoperative scale at 1 was significantly higher in group 1 with a mean of 10.2±1.9 than in group 2 (9.5±1.4) and group 3 (5.9±1.4) (P<0.001). The agitation score at 5 h was significantly higher among group 1 with a mean of 2.77±0.67 than group 2 (2.56±0.64) and group 3 (2.03±0.96) (P<0.001). Also, agitation scores at 10 and 15 h were significantly higher in group 1 (3.36±0.63, 4.2±0.66) than in group 2 (3.2±0.66, 3.79±0.73) and group 3 (1.74±0.88, 2.03±1.04), respectively (P<0.001).

Conclusion

Melatonin premedication decreased the agitation scale postoperatively. The decrease was significantly higher in high doses in preventing emergence agitation in children. High-dose melatonin compared with low dose might have a significant effect in preventing emergence agitation.

Published: July 2024

Introduction:

Singapore faces an increasingly aged population with complex multimorbidity and psychosocial impairment. This change in demographic is challenging for existing healthcare systems. Breaks in care coordination and continuity result in poor health outcomes, increased acute care utilisation and higher healthcare costs. We proposed a patient empanelment approach adapted for the Singapore context based on the University of Chicago Comprehensive Care Physician model.

Methods:

This retrospective quasi-experimental, matched-controlled observational study sought to assess the effectiveness of the Enhanced Comprehensive Care Programme (ECCP) in reducing acute care utilisation at National University Hospital, Singapore. The primary outcomes were the number of hospitalisations and emergency department (ED) visits 6 months pre- and post-enrolment in ECCP. We used propensity score matching to balance prior healthcare utilisation between the intervention and control groups.

Results:

Fifty-seven participants were recruited in the programme between October 2019 and April 2020. There was a reduction in the mean number of hospitalisations after intervention compared to before intervention (0.58 ± 1.03 vs. 1.90 ± 1.07, P < 0.001). There was also a reduction in the mean number of ED visits (0.77 ± 1.05 vs. 1.96 ± 1.14, P < 0.001). In the propensity-matched cohort, the mean number of hospitalisations was reduced in the intervention group (from 1.92 ± 1.07 to 0.58 ± 1.03, P < 0.001) compared to the control group (from 1.85 ± 0.99 to 1.06 ± 1.17, P = 0.04).

Conclusion:

This observational study shows the potential benefits of ECCP healthcare redesign to reduce acute care utilisation.

Authors: Nafie Mahmoud , Chadbunchachai Weeraput , Lapa Christo , Gregory Stephen , Nunoo-Mensah Joseph William
Published: July 2024

Nonsteroidal anti-inflammatory drugs (NSAIDs) are well known to cause ulcers and bleeding in the upper gastrointestinal tract. Furthermore, several studies to date have demonstrated that NSAIDs may also cause ulcers in the lower gastrointestinal tract, or the bowel, resulting in small bowel bleeding. The diagnosis and management of bleeding in the small bowel region pose a significant challenge. Here, we present the case of a 30-year-old female who presented to the hospital with lower gastrointestinal bleeding after taking an NSAID for a prolonged period. The results of all investigations, including computed tomography angiography, esophagogastroduodenoscopy, colonoscopy, and digital subtraction angiography, were negative. The patient was transferred to the operating room for an on-table colonoscopy and surgical intervention because of continuous bleeding and hemodynamic instability. During the operation, a suspected bleeding site was located in the terminal ileum, leading to the resection of the small bowel, which revealed ulcerative lesions. NSAIDs are believed to have caused the ulcer in this patient, as evidenced by all the available information, including the pathological results.

Published: July 2024

Alluvial forest environments are vulnerable, representing one of the most degraded ecosystems globally. This study evaluated the dynamics of an urban Alluvial Mixed Ombrophilous Forest and the invasion of Ligustrum lucidum W.T.Aiton (Oleaceae) in Guarapuava-PR, Brazil. Diameter at Breast Height (DBH ≥ 5 cm) and height measurements of tree individuals were carried out in 72 study plots of 100 m² each, between 2011 and 2022, and phytosociological descriptors and Relative Growth Rates and Mortality Rates were calculated. Analysis of Variance compared the abundance of the invader over the years, and Pearson correlation investigated its relationship with native species’ richness. Other comparisons used Generalized Linear Models, with Bonferroni correction at 5% significance level. L. lucidum showed similar mean diameter to the native tree community, but its mean height was significantly higher. Gymnanthes klotzschiana, Matayba elaeagnoides, and L. lucidum had higher phytosociological descriptors and sociological position values. The growth rate of L. lucidum was higher along with Casearia decandra, and the alien species had a low mortality rate compared to Zanthoxylum rhoifolium and Ocotea puberula. However, there was no significant increase in the abundance of L. lucidum, although a weak negative correlation between native species richness and invader abundance was observed. The invasion degree indicated a 5% increase in the alien population during the study period. This study provides a basis for investigations into the dynamics of alluvial forests and the biological invasion process.

This study characterized the physical integrity, hydromorphology, and limnology of ten urban streams in the Southwestern Amazon. The objective was to investigate how these characteristics covary and identify threats to the health of these ecosystems. The physical integrity of the streams was assessed using a Habitat Integrity Index (HII), hydromorphology based on width, depth, flow, and substrate type, and limnological characterization through 14 physico-chemical parameters during dry and rainy seasons. Three streams were classified as preserved, two as intermediate, and five as degraded. Anthropogenic alterations were observed in hydromorphological characteristics, especially in width, depth, and substrate type across different integrity categories. Limnological analysis revealed that chemical and biochemical oxygen demands, ammoniacal nitrogen, nitrate, dissolved iron, and sulfides exceeded the limits established by Brazilian water quality regulations (CONAMA 357/2005). The alteration of these parameters reveals that the primary threat to the integrity of these ecosystems is sewage collection and treatment issues, reflecting the absence of basic sanitation. Redundancy Analysis (RDA) indicated the influence of specific substrate types on parameters in degraded streams, while preserved streams showed a correlation between dissolved oxygen with riparian forest conditions and the absence of anthropogenic influence. Cluster analysis emphasized the importance of integrating environmental, hydromorphological, and limnological metrics for a comprehensive assessment of ecosystem health. Given the heterogeneity of Amazonian aquatic ecosystems, this study may contribute to the establishment of criteria based on regional characteristics for accurate assessment and guidance of public policies aimed at protecting and ensuring the integrity of these ecosystems.

Purpose This study aims to evaluate the treatment approaches and locoregional patterns for adenoid cystic carcinoma (ACC) in the breast, which is an uncommon malignant tumor with limited clinical data.Materials and Methods A total of 93 patients diagnosed with primary ACC in the breast between 1992 and 2022 were collected from multi-institutions. All patients underwent surgical resection, including breast-conserving surgery (BCS) or total mastectomy (TM). Recurrence patterns and locoregional recurrence-free survival (LRFS) were assessed.Results Seventy-five patients (80.7%) underwent BCS, and 71 of them (94.7%) received post-operative radiation therapy (PORT). Eighteen patients (19.3%) underwent TM, with five of them (27.8%) also receiving PORT. With a median follow-up of 50 months, the LRFS rate was 84.2% at 5 years. Local recurrence (LR) was observed in five patients (5.4%) and four cases (80%) of the LR occurred in the tumor bed. Three of LR (3/75, 4.0%) had a history of BCS and PORT, meanwhile, two of LR (2/18, 11.1%) had a history of mastectomy. Regional recurrence occurred in two patients (2.2%), and both cases had a history of PORT with (n=1) and without (n=1) irradiation of the regional lymph nodes. Partial breast irradiation (p=0.35), BCS (p=0.96) and PORT in BCS group (p=0.33) had no significant association with LRFS.Conclusion BCS followed by PORT was the predominant treatment approach for ACC of the breast and LR mostly occurred in the tumor bed. The findings of this study suggest that partial breast irradiation might be considered for PORT in primary breast ACC.

Authors:   University of Belgrade, Faculty of Transport and Traffic Engineering, Lipovac Krsto , Nešić Miladin ,   University of Criminal Investigation and Police Studies
Published: July 2024

The Government of the Republic of Serbia adopted the National Road Safety Strategy for the period 2023-2030. and the Road Safety Action Plan for the period 2023-2025. For the successful implementation of these strategic documents, it is necessary that all stakeholders understand their role and be committed to the implementation of measures and activities of which they are the bearers or in which they participate as partners. The paper presents a model of analysis of the National strategy and Action Plan, with the aim of defining the place and role of local self-government units. Within each of the five pillars of road safety, measures are set out, and within the measures, activities for which the local self-government unit is responsible or in which the local self-government unit should participate as a partner. According to this model, all stakeholders of road safety should recognize their role, select the measures and activities that they should implement, and then prepare and implement their strategies and action plans in the observed period, as well as establish cooperation relationships. and coordination with other subjects.

The basic prerequisite for the successful management of any system, including the road safety system, is knowledge of the existing situation, because in this way the key problems of that system can be observed. In the road safety system, in addition to knowing data on final outputs, i.e. data on road accidents and the consequences of road accidents, it is necessary to know data on the attitudes of road users and data on road safety indicators, because attitudes and indicators of traffic safety can very clearly and precisely indicate problems, and on the other hand, as a rule, have a highly correlative relationship with the final outputs. In this regard, the Republic of Serbia recognized the importance of monitoring road safety indicators as early as 2013. After a decade of measuring road safety indicators in the Republic of Serbia and numerous challenges that accompanied the establishment of this process, this paper presents the chronology of measuring road safety indicators, as well as the latest conclusions of a detailed correlative analysis between indicator values and final outputs.

Persons with disabilities face numerous challenges in their daily lives. One of the most significant issues is accessibility to transportation. The problem of transportation accessibility is primarily manifested through reduced mobility compared to the rest of the population. The aim of this paper is to identify the most significant problems that diminish the mobility of persons with disabilities and to propose appropriate measures. To achieve better systematization, the mobility of persons with disabilities is divided into non-motorized and motorized trips. In the case of non-motorized trips, special emphasis is placed on issues related to the accessibility of transportation infrastructure. Within motorized trips, measures are divided into those related to passenger car and public transportation vehicles. Problems related to passenger car are analysed for both the driver’s and passenger’s characteristics. Additionally, autonomous vehicles have been recognized as a separate category of vehicles that will significantly improve the mobility of persons with disabilities in the future. The measures presented in this paper serve as a basis for raising awareness among decision-makers at the local government level to enhance the mobility of persons with disabilities.

More than 100,000 tractors in the Republic of Serbia are in use without any protective structures for drivers in the event of the tractor overturn. The number of victims due to tractor overturns is increasing. The implementation of regulation on the obligation of built-in cabins or protective frames on tractors, which has been postponed several times, should be put into effect in 2025. Since 2019, Road Traffic Safety Agency of the Republic of Serbia has been actively conducting research aimed at universal solution for the construction of the protective frame, as well as finding ways to overcome the absence of tractor driver activity in terms of equipping tractors with appropriate protective structures. During 2023, 4652 protective frames have been distributed. Further research is being conducted for new additional solutions for the construction of the protective frame that can be applied to several different models of the most common tractors. An area of research has been opened on ways to further increase tractor safety in terms of securing the driver's position in the protective space by installing seat belts. The losses that occur in our society due to fatal tractor overturns without the mentioned protective structures are enormous. A joint effort with local overnments can increase the awareness of tractor owners and achieve a better level of their protection.

Research on Improving Middle School Choice Lottery System from the Perspective of Preference Utilitarianism

This study analyzes the results of the middle school allocation in Region A for the 2023 academic year and proposes a new allocation method that can significantly improve the results. We analyze the middle school application data for Region A and find that some schools have more first-choice applicants than seats, while others have fewer first-choice applicants than seats. However, the application rates for second-choice schools exceeded 100% of the capacity for all schools, indicating that there were no universally unpopular schools. Nevertheless, 113 students were not assigned to either their first or second-choice schools in the 2023 academic year in Reagion A.
This study proposes a new assignment method that maximizes student satisfaction by efficiently assigning students to their first-choice schools while taking into account the characteristics of regions where there is a herding effect toward applying to their first-choice schools, but where there are no universally unpopular schools that students would avoid when considering their second-choice schools. The new assignment method effectively reduces random assignments by finding the optimal assignment for students from a preference utilitarian perspective. Simulations show that the new assignment method we propose assigns all students in Region A to their first- and second-choice schools. Furthermore, when we improve the apply method to allow students to apply to multiple schools with the same ranking, the new assignment method can also assign all students to their first-choice school if more than 80% of students apply to two schools in their first choice.
