Published: June 2020

The Surgical Pleth Index (SPI) is a multivariate index derived noninvasively from finger plethysmographic signal. It has been demonstrated to correlate with surgical stress intensity. So, we examined these beneficial effects of SPI guided anaesthesia to determine the amount of intraoperative fentanyl consumption and haemodynamic stability in laparoscopic surgeries under general anaesthesia. After obtaining institutional ethical clearance and patient informed consent, A total of 100 Patients (20-65yrs) posted for laparoscopic surgeries under general anaesthesia were randomly allocated to the SPI and conventional analgesia group (50 patients each). In SPI group, SPI value &#62;50; In conventional group, rise in heart rate(HR), mean arterial pressure (MAP) 20% above baseline were the criteria for fentanyl administration. Fentanyl 0.5 µg/kg is administered in each group for an event persisting for 5 min. Intraoperative fentanyl consumption, hemodynamic stability and postoperative pain for 1 hour were observed. Comparison analysis was performed for total intraoperative fentanyl consumption using t-test. Correlation analysis performed using the Pearson test and p- value &#60;0.05 was considered significant.Total intraoperative fentanyl consumption was lower in SPI group than in the conventional group (108.30±21.84 µg vs 125.70±24.87 µg; p=0.0003) and it was statistically significant with good haemodynamic stability. Postoperative pain scores were comparable in both the groups. The postoperative fentanyl consumption in SPI group was 14.4 ± 1.7 µg and in conventional group was 19.4± 7.0 µg.Compared with conventional analgesia, SPI guided analgesia resulted in lower intraoperative fentanyl consumption and more stable haemodynamics.

Incidence of awareness in patients undergoing cardiac surgery is up to 23% compared to its incidence of 1% during general surgery. In our institute we conducted study in 40 patients undergoing valve surgeries and compared volatile agent vs. conventional method with help of BIS monitoring. Partly because of the difficulty of administering volatile agents during cardiopulmonary bypass (CPB), total intravenous anaesthesia (TIVA) has been a popular technique used by cardiac anaesthetists in the last few decades. However, the possibility that volatile agents cut back mortality and the incidence of myocardial infarction by preconditioning the myocardium has stimulated a revival of interest in their use for cardiac anaesthesia. We observed the higher BIS values were seen in conventional group with requirement of higher dose of propofol as a rescue to avoid intraoperative awareness. The haemodynamics were steadily maintained in isoflurane group. The inotrope score was less in isoflurane group indicating myocardial protective effect of isoflurane. In conclusion, in patients undergoing heart surgery with CPB, the findings of this study indicate that appropriate use of isoflurane to maintained depth of anaesthesia during CPB should be monitored with use of BIS and ETAC.

During laparoscopic procedures, hemodynamic stability is of great concern. This study was carried out to evaluate hemodynamic Changes with different intra- abdominal pressure (IAP) for laparoscopic cholecystectomy using Advanced Cardiac Output (FloTrac) Monitoring. In this Prospective, randomized and observational study, total 90 patients ASA grade I, II scheduled for laparoscopic cholecystectomy were randomly allocated to three groups: Group I :10-12mm hg, groupII-13-15mmhg, Group III- &#62; 15mmhg. Central venous line and arterial cannula was secured before induction and connected to FloTrac monitor. Heart rate (HR), Cardiac index (CI), Systemic vascular resistance index (SVRI), Stroke volume variation (SVV), Oxygen saturation (SPO2) were monitored at various interval. For Statistical analysis student t-test and ANOVA test were used. At all time intervals, HR of Group I was found to be lower than Group II and Group III except at insufflation. CI (Cardiac Index) of Group I was also found to be lower than that of Group II and that of Group III was lower than that of Group II at all time intervals. At all time periods values of SVRI, SVV of Group I were found to be lower than that of Group II and Group III. SVRI, SVV of Group II were found to be lower than that of Group III. IAP value above 15mm Hg seems to affect the hemodynamics significantly. Study showed that the IAP rise from 10-12 to 13-15 does not influence hemodynamics significantly, and could be adjudged relatively safe.

The advent of laparoscopic surgery has benefited the patient and surgeon; however creation of pneumoperitoneum for same has bearings during the perioperative period. These effects of pneumoperitoneum are associated with significant hemodynamic changes, increasing the morbidity of the patient. Dexmedetomidine, a new α2 agonist provides stable hemodynamic condition, good quality of intra operative analgesia and prolonged post-operative analgesia with minimal side effects.: A total of 74 patients of either sex, planned for laparoscopic cholecystectomy were included. The patients were randomly divided into two groups of 37 each. GROUP D received Injection Dexmeditomedine 5µg (0.05ml) is diluted in 0.5ml of cerebrospinal fluid and injected intrathecally. A 5minutes interval is given for recording of post injection hemodynamic parameters prior to general anaesthesia. Patients will be premedicated with Injection glycopyrrolate 0.04 mg/kg, Injection midazolam 0.02 mg/kg and Injection Fentanyl 2µg/kg intravenously. After adequate preoxygenation, conventional general anaesthesia will be given to the patients. GROUP ‘E’: Conventional general anaesthesia alone. Heart rate (HR), systolic blood pressure, diastolic blood pressure and mean arterial pressure (MAP), ETco2 were recorded preoperative, after study drug, after induction, after pneumoperitoneum at 5 min intervals, post pneumoperitoneumIn group D, there was no statistically significant increase in HR and blood pressure after pneumoperitoneum at any time intervals and there was significant increase in time for first rescue analgesic, intraoperative fentanyl requirement, whereas in Group E, there was a statistical significant increase in MAP after pneumoperitoneum at 5, 10 and 15 min and HR during the whole pneumoperitoneum period.Dexmedetomidine 5 µg given intrathecally improves the hemodynamic stability, decreased intraoperative requirement of fentanyl and the duration of postoperative analgesia and also provides an analgesic sparing effect in patients undergoing laparoscopic abdominal surgery.

Peripheral nerve blocks (PNB) are getting significant recognition for intraoperative and publish operative pain control because of their distinct advantage over general anaesthesia anesthesia. There are different ways to a brachial plexus block. The coracoid infraclavicular approach is feasible in almost all patients. A prospective randomized control trial was performed to compare the clinical effect of infraclavicular and supraclavicular brachial plexus block using a nerve stimulator for upper limb surgery. Sixty patients receiving upper limb orthopedic surgery under infraclavicular or supraclavicular brachial plexus block were enrolled in this study. The supraclavicular brachial plexus block was performed using nerve locater and ultrasound technique with 40 ml of 0.5% bupivacaine 1.5 mg/kg, ligocaine 2% with adrenaline 4mg/kg and distilled water. This study observed which nerve types were stimulated, and scored the sensory and motor blockage. The quality of the block was assessed intra-operatively and postoperatively with modified Lovette rating scale and McGill’s pain score. The duration of the sensory, motor block and the complications were assessed. The patient’s satisfaction with the anesthetic technique was assessed after surgery. In our study we observed similar effect in both infraclavicular and supraclavicular brachial plexus block. The infraclavicular approach may be preferred to the supraclavicular approach as complications are fewer with infraclavicular approach but expertise is needed in infraclavicular block.

Pregnant women are always considered full stomach with high incidence of nausea and vomiting. Anti-emetic efficacy of Ondansetron has been proved in various studies. The aim of this present study is to evaluate efficacy and safety of chewing gum as an alternative to Ondansetron in prevention of postoperative nausea and vomiting (PONV) in parturients undergoing elective LSCS under spinal anesthesia. One hundred pregnant women who were found eligible as per inclusion and exclusion criteria were randomized into two equal groups by simple randomization into Group A (n=50) who were given sugar free chewing gum which was to be chewed for 30 minutes three times a day starting immediately after cesarean section and Group B (n=50) who received Inj. Ondanse tron 4mg twice a day post operatively. The outcome measures were episodes of post-operative nausea and vomiting at 6, 12, 18 and 24 hours in both groups, relief of PONV and acceptability of treatment. The secondary outcome measures time to first flatus. Statistical analysis was done through relevant tests using SPSS 16.0. There was no statistically significant difference between the two groups in terms of demographic characteristics such as age, gravidity parity, duration of surgery and type of cesarean section. The incidence of nausea and vomiting was significantly less in Group A compared with Group B at 6 and 12 hours post operatively (p &#60; 0.001). There was no significant difference of this variable at 18 and 24 hours in both groups. The mean average of the first passage of flatus in group A was 20.3±2.01 hours versus 29.6±2.51 hours in Group B (P&#60;0.0001) was significantly shorter compared to the group B. Gum chewing after cesarean section is safe, well tolerated, and acceptable for prevention of post-operative nausea and vomiting and rapid resumption of intestinal motility and has potential impact on reducing the overall healthcare costs in case of routine implementation.

Published: June 2020

General anaesthesia with endotracheal intubation is the definite way of securement of airway. Tracheal extubation is associated with increased sympathoadrenal response which leads to deleterious consequences in susceptible patients. This study aims to evaluate the efficacy of dexmedetomidine 0.6mcg/kg iv in the suppression of sympathoadrenal response to tracheal extubation.Sixty participants aged between 18-55yrs belonging to ASA 1 or 2 were randomly allocated into 2 groups. Group Dxd received injection Dexmedetomidine 0.6mcg/kg iv and Group Cl received normal saline. Heart rate, systolic and diastolic blood pressure were recorded at baseline, 2, 5, 8 minutes after drug infusion, at extubation and 1,3,5,8,10 and 15 minutes post extubation. Group Dxd showed lower heart rate, systolic and diastolic blood pressure at extubation, and till 15minutes postextubation compared to Group Cl.Dexmedetomidine 0.6mcg/kg iv effectively attenuates the sympathoadrenal response to tracheal extubation.

<p align="justify">During the spray forming process of die steel, the gas flow field of nozzle atomizer has an important influence on the atomization effect of metal solution and the shape and performance of deposited billet. In this paper, the finite element analysis method was used to study the flow field distribution of the annular slot type restricted nozzle. The results showed that the negative pressure area was formed at the front of the atomizing gas outlet of the nozzle; the negative pressure area was enlarged and the negative pressure value was increased with the increase of the extending position of the liquid guide pipe and the atomizing pressure; when the atomizing pressure was 0.5MPa and the extending position of the liquid guide pipe was 7mm, the negative pressure value of the front of the liquid guide pipe could reach-38650Pa and the gas flow rate could reach 191.4m/s; the back-injection could be effectively avoided by optimizing the appropriate process parameters. And the damage of atomizing nozzle could be reduced.</p><p align="justify"> </p>

<p>Polyhedral BiVO<sub>4</sub> was prepared by hydrothermal-calcination two-step method. The physicochemical properties of polyhedral BiVO<sub>4</sub> were characterized by XRD, TG/DTA, SEM and UV-vis DRS. The photocatalytic properties of the samples were investigated by using 10 mg/L methylene blue (MB) as the target degradant. The experimental results showed that the prepared polyhedral BiVO<sub>4</sub> is monoclinic. The morphology is about 10 μm polyhedral block. The pure phase BiVO<sub>4</sub> has strong visible light absorption capacity. Under visible light irradiation, the prepared BiVO<sub>4</sub> can degrade 90% of MB within 40 min. Moreover, the photocatalytic performance was further improved by forming a BiVO4/BiOCl heterojunction, and the kinetic reaction rate was 1.5 times that of the pure phase BiVO<sub>4</sub></p>

Published: June 2020

Purpose of the study: This paper investigated the extent to which the awareness and knowledge of financial bootstrapping determined the techniques used by immigrant entrepreneurs in the retail clothing sector in the Cape Town metropolitan area.
Methodology: A quantitative research approach was used to collect and analyze data. Through self-administered questionnaires, 135 respondents participated in the study. The data obtained were analyzed using the Statistical Package for the Social Sciences (SPSS) software, version 24.
Main Findings: The results point to the fact that while the respondents made use of a wide range of financial bootstrapping techniques, there was no sufficient evidence to support the fact that this was influenced by their level of awareness and knowledge of these methods. Even the respondents with limited or no knowledge of the concept of financial bootstrapping applied the strategies in their businesses.
Applications of this study: This paper may directly benefit immigrant entrepreneurs, besides informing future research and policy.
Novelty/Originality of this study: This paper validates the extent to which awareness and knowledge of financial bootstrapping influences the strategies utilized by immigrant entrepreneurs in South Africa.

Published: June 2020

Purpose of the study: The study investigates the mediating role of moral identity between psychological contract breaches, as an antecedent of intention to sabotage in the public sector organization in Fiji.
Methodology: A self-completed written survey and a random sampling method were used in collecting data from 340 employees of various public sector organizations in Fiji Island. The data were analysed through SPSS and SEM for model fit in AMOS.
Main Findings: The findings revealed that there is a positive relationship between psychological contract breach and intention to sabotage the service in the public sector organization (β=0.604, p < 0.01). The moral identity had a significant mediating relation between the two variables. (β=0.223, p < 0.01), as such, high moral identity partially mediated the relationship between psychological contract breaches and employee intention to sabotage service.
Applications of this study: The result of the study is has a significant impact on improving organizational effectiveness and at the same time using moral identity as an indicator to evaluate employees in public sector organizations. Besides, organizations can also integrate ethics into training human resources.
Novelty/Originality of this study: As neglected by prior studies, this study highlights the importance of recognizing the role of moral identity in organizational development, especially during a crisis. Furthermore, human behaviors do not operate as tabula rasa but the subsequent effect of organizational adversities such as PCB.

De 613 pacientes que ingresaron al Programa Materno Infantil del Centro de Salud Siloe en Cali (Colombia) (522) más o menos el 70% fueron del Distrito y corresponden al 72% de la población de gestantes, lo cual dá una alta cobertura compara con la obtenida por Centros de Salud en el área de Primops.Se obtuvo el 82.4% de la información completa con datos del niño, lo cual es un buen resultado en este tipo de investigaciones en comunidad.Se trata de una población de gestantes menores de 30 años, con un promedio, de 2 embarazos y en unión libre la gran mayoría.El 19.7%, tuvieron algún riesgo, observándose un aumento de la frecuencia con la edad. Siendo el 14.4% de bajo riesgo y el 5.3% patología severa en su primera consulta.Las gestantes con clasificación de alto riesgo tuvieron una primera consulta significativamente más tardía que la población total; cuando consultan por primera vez tienen en promedio 2 meses más de gestación.La pre-eclampsia, anemia, gran multiparidad, lues latente y cesárea previa son la patología más frecuentemente detectada.El 90% de las gestaciones terminaron en parto normal, el resto corresponden a parto intervenido, cesáreas y abortos.El 90% fueron partos institucionales, lo cual muestra la motivación que se les hace a las gestantes durante su control prenatal.El 3% dé los partos “clasificados” inicialmente como de mayor riesgo, no lo tuvieron en el sitio adecuado y un 4.63% lo tuvieron en el hospital, sin mayor justificación, lo cual nos dá un error en el sitio del parto del 7.63%.El 7.3% de las pacientes clasificadas sin riesgo inicialmente se complicaron durante el trabajo de parto y fueron remitidas al hospital. Dándonos un riesgo total prenatal más intra-parto de 27%, cifras muy similares a las encontradas en la población de gestantes en el Instituto de los Seguros Sociales de Cali.
