Authors: Gadalla Raouf Ramzy , Hilal Abdou Amr Mohammed , Mohamed Abdellatif Nourhan Osama 
Published: July 2024

Abstract

Background
The novel coronavirus, designated SARS-COV-2, has caused a pandemic of respiratory illness termed coronavirus disease 2019 (COVID-19). One of the key issues has been the very high number of patients presenting to hospitals that clearly overwhelms the capacities available, especially the need for critical care support. Therefore, early and effective predictors of clinical outcomes has been urgently needed for risk stratification of COVID-19 patients.

Objective
To evaluate the value of D-dimer blood levels on intensive care unit (ICU) admission as a predictor of disease severity and mortality in COVID-19 ICU admitted patients.

Patients and Methods
The current study included the records of 465 patients who were admitted to Ain Shams University isolation hospitals ICU during the time period between 1/1/2021 and 1/6/2021.

Results
There are many studies that have tried to correlate between D dimer levels and COVID-19 outcome. by comparing these studies we find that the value of D-dimer levels as a predictor of disease outcome is quite obvious. Trying to find opposing literature to the previous findings is a difficult process as the great majority of the literature that tried to link D-dimer levels to COVID -19 outcomes have eventually come to the same conclusion which is proving that there is a significant relationship between D-dimer levels and disease outcome and that morbidity and mortality risk increases with elevated D-dimer levels.

Conclusion
In COVID-19 patients, D-dimer levels on admission to ICU and 48 hours afterwards can be a reliable indicator of the disease prognosis as high D-dimer levels are associated with increased need for mechanical ventilation and mortality with cutoff values 1.39 for initial D-dimer and 1.02 for D-dimer level after 48 hours.

Abstract

Background
Analgesia is very important after cesarean section because it improves ambulation and enables the mother to give optimal care for the neonate in the immediate postoperative period. Opioids are widely used, but their side effects limit their application. Transversus abdominis plane (TAP) block has been proved to be a useful and safe alternative technique to provide analgesia following abdominal surgeries.

Objective
to compare the duration of analgesia produced by two drugs fentanyl and dexmedetomidine as adjuvants to bupivacaine in TAP block under ultrasound-guidance after cesarean section in a randomized controlled trial.

Patients and Methods
In our study, 40 patients were randomly divided into 2 equal groups. The control group received 50 mcg of fentanyl added to bupivacaine on each side. The study group received 50 mcg of dexmedetomidine added to bupivacaine on each side. All patients received equal volumes. Our study showed that addition of a 50 mcg of dexmedetomidine to bupivacaine in ultrasound-guided TAP block has statistically significant effect on the hemodynamic stability of the patients. In addition, dexmedetomidine prolonged the duration of analgesia significantly, as proved by the time of request of first rescue analgesia. Moreover, in dexmedetomidine group, postoperative analgesic requirements were greatly lesser than that of fentanyl group. This makes dexmedetomidine with bupivacaine more superior than the use of fentanyl with bupivacaine.

Results
In our study, the total rescue analgesia consumed in 24 h postoperatively which was pethidine was less in the TAP-D group (75 ± 25.6 mg) than in the TAP-F group (112.5 ± 42.5 mg). In this study, regarding the measurement the time to the first dose of analgesic received postoperatively, there was a long duration needed in TAP-D group compared to the TAP-F (control group) with the p- value &lt; 0.0001. The time to the first rescue analgesia in the TAP-D group was (659.7 ± 20.99 min.) and for the TAP-F group, it was (512.75 ± 18.1 min.).

Conclusion
Dexmedetomidine delayed the time to first rescue analgesia when added to bupivacaine in TAP block using ultrasound-guided technique and improved patients’ outcome with decrease in the total pethidine consumption and more hemodynamic stability in comparison to the addition of fentanyl to bupivacaine.

Abstract

Background
Deadly pandemics and disease emergences are not new phenomena: they have been challenging human existence throughout recorded history. Some have killed sizeable percentages of humanity, but humans have always searched for, and often found, ways of mitigating their deadly effects.

Objective
to compare between standard dose methyl prednisolone (1-2 mg/kg) and mega dose methyl prednisolone (0.5 g to 1g) as regards outcome reflected by mortality rate, percentage of mechanically ventilated patients and ICU length of stay of COVID 19 patients admitted in ICU.

Patients and Methods
After obtaining approval from the Research Ethical Committee of Ain Shams University (FMASU MS 41/2022) this study was obtained from Ain Shams University Isolation Hospitals records. Group A: Patients admitted in ICU, COVID PCR positive and requiring oxygen therapy who received methyl prednisolone standard dose (1-2 mg/kg). Group B: Patients admitted in ICU, COVID PCR positive and requiring oxygen therapy who received methyl prednisolone mega dose (0.5-1 g per day).

Results
This study showed that there is no significant statistical difference between receiving standard dose and mega dose methyl prednisolone as regards mortality rate or need for mechanical ventilation.

Conclusion
This study showed that there is no significant statistical difference between receiving standard dose and mega dose methyl prednisolone as regards mortality rate or need for mechanical ventilation. But showed significant statistical difference as regards ICU length of stay denoting that patients received mega dose methyl prednisolone showed increased ICU stay.

Authors: Reyad Mostafa Kamel , Ahmad Mohamed Saleh , Koraitam Ahmed Farouk , Hanafy Abdelrahman Mohamed 
Published: July 2024

Abstract

Background
Total hip arthroplasty (THA) are common surgical procedures for treatment of the degenerative disorders and traumatic diseases. However, a majority of patients often experience moderate to severe postoperative pain after THA. Postoperative pain control has a significant impact on earlier ambulation, initiation of physiotherapy, and better functional recovery. In addition, effective pain control would lower the length of hospital stay and the risk of thrombotic events which improves patients’ satisfaction.

Objective
To assess the efficacy and safety of FICB compared with FNB.

Patients and Methods
After approval of anesthesiology department scientific and ethical committees in Ain Shams University Hospitals, patients were included in the study, and were divided into two groups (n = 20; each); group FICB and FNB group. Group FICB: Patients (n = 20) of this group received ultrasound guided Fascia iliaca compartment block (FICB) before spinal anesthesia using 20-40 ml of 0.25% bupivacaine. Group FNB: Patients (n = 20) of this group received ultrasound guided femoral nerve block (FNB) before spinal anesthesia using 20-40 ml of 0.25% bupivacaine.

Results
The two groups were adequately monitored and assessed post-operatively and they were compared regarding analgesic outcome by using the visual analogue scaling system, besides, recording time for first call for rescue analgesia. Demographic data, post-operative hemodynamics, and sedation score were also assessed.

Conclusion
Fascia iliaca compartment block is effective for pain relief during the early post- operative period after total hip arthroplasty. Meanwhile, it can reduce the cumulative meperidine consumption and the risk of opioid-related adverse effects.

Published: July 2024

Abstract

Background
term “emergence delirium” first appeared in medical literature in early 1960s. While it is frequently used interchangeably with emergence agitation, it is described as temporary dissociated state of consciousness following anaesthesia discontinuation.

Aim and Objectives
aim was to study the role of pre-emptive Chlorpheniramine as an adjuvant to paracetamol in the prevention of emergence agitation in orofacial cleft repair surgeries. Studied cases& techniques: study was prospective, Randomized, Double-Blind Clinical research done at Ain-shams University Hospitals, Cairo, Egypt for 6 months after Medical Ethical Committee approval for children within 3 month up to 18 years with cleft lip or/with cleft palate.

Results
On comparison of facial express score between group A & group B, group A showed significant decrease in facial express score compared to group B as the median (IQR) facial express score in group A was 2.0 (2.0- 4.0) and 4.0 (2.0-8.0) in group B.

Conclusion
We deduced that preoperative chlorpheniramine 0.2 mg/kg and paracetamol 15mg/kg before skin incision is effective medication that can be used to stop or decrease severity of emergence agitation while causing minimal cardio- respiratory depression. It also enhanced quality of healing in post-anesthesia care unit.

Published: July 2024

Abstract

Background
Knee arthroscopy is one of the most frequently performed interventions in orthopedic surgery that is commonly performed on a day-case basis. It allows the diagnosis and management of a wide range of knee problems without making a large incision, thus decreasing soft tissue trauma. However, postoperative pain is a common upsetting symptom following arthroscopic knee surgery that if inadequately treated, leads to prolonged duration of the functional rehabilitation of the knee, recovery time and the length of hospital stay thus a significant increase in the medical care costs.

Aim of the Work
To compare the adjuvant effect of adding dexmedetomidine and/or dexamethasone to bupivacaine while using facsia iliaca block for knee arthroscopy and their efficacy in achieving postoperative analgesia.

Patients and Methods
The type of study was a prospective double – blinded randomized controlled Trial conducted in Ain Shams University hospitals, Cairo, Egypt at 6 months. Patients aged 20 to 60 years scheduled for elective knee arthroscopy under spinal anesthesia were included to receive FICB.

Results
In general, there was no significant difference between the three study groups regarding general patient characteristics as well as operative time. That ensured proper randomization conducted between our study groups. Additionally, that should nullify any bias that may have skewed the results in favor of one group rather than another one. There was statistically significant difference between groups according to heart rate from after 2hrs to after 24hrs this was also observed while measuring the systolic blood pressure and diastolic blood pressure but there was no significant difference between group B and C.

Conclusion
Our study shows that adding Dexmedetomidine and/or Dexamethasone (8mg) to Bupivacaine for FICB significantly prolonged the duration of block and decreased the requirement of rescue analgesics as compared to patients who received Bupivacaine alone. FICB is relatively easy and safe to perform. In our study we did not encounter any complication while doing the procedures and also by adding dexmedetomidine and/or dexamethasone (8mg).

Published: July 2024

Abstract

Background
controlled (deliberate/induced) hypotension is a technique by which the arterial blood pressure is lowered in a controllable manner to reduce surgical blood loss and improve the operative field visibility. There are pharmacological and nonpharmacological techniques for inducing hypotension. The nonpharmacological methods for deliberate hypotension include positioning and positive pressure ventilation to control venous return.

Aim of the Work
to evaluate the efficacy of dexmedetomidine (DEX) as a hypotensive agent in comparison to nitroglycerin (NTG) in FESS regarding the bloodless field, reduction of mean arterial blood pressure, decrease inhalational anesthetic requirements (MAC), decrease perioperative opioid requirements, increase the time to first postoperative analgesic request and recovery profile and increase hemodynamics stability.

Patients and Methods
we conducted this study on 20 patients who were planned to perform functional endoscopic sinus surgery and were randomly distributed into 2 equal groups: 10 patients received dexamedotomidine and equal number of patients received nitroglycerine. Serial measurements of mean arterial blood pressure and heart rate were obtained and records between both groups were compared.

Results
There were statistically significant differences between both groups regarding heart rate as mean values of heart rate were lower among dexamedotomidine group. There were no statistically significant differences between both groups regarding mean arterial blood pressure values at different time points during the operation. Regarding the period after stopping infusion, mean values of heart rate and blood pressure were lower among dexamedotomidine group than nitroglycerine group after 5 minutes and after 10 minutes and the differences had statistically significant differences. Regarding postoperative period, both groups were comparable regarding heart rate and blood pressure immediately postoperative.

Conclusion
From the results of this study, we could conclude that both Dexmedetomidine and Nitroglycerin can be effectively used in induced hypotensive anesthesia for ENT surgery as FESS. Both groups were comparable with intra operative MAP with no statistically significant differences. This study also show that Dexmedetomidine has added advantages as better haemodynamic stability than Nitroglycerin (No rebound HTN, no tachycardia). Has sedative and analgesic effect, reduce requirement of anesthetic agents and perioperative analgesia. Postoperative recovery score (Time to reach modified Aldert score more than nine significantly higher. Postoperative complication as nausea and vomiting is less.

Published: July 2024

Abstract

Objective
The Pringle maneuver used during hepatectomy causes ischemic reperfusion injury to the liver remnant. In this study, we compared the effect of maintenance of general anesthesia with propofol dexmedetomidine intravenous infusion versus desflurane inhalational anesthesia on post hepatectomy hepatocellular injury in patients undergoing partial hepatectomy during the first six postoperative days.

Method
Group A (15 patients) received total intravenous anesthesia with a combination of propofol and dexmedetomidine for anesthesia maintenance. and Group B (15 patients) received desflurane for anesthesia maintenance. Alanine aminotransferase (ALT), aspartate aminotransferase (AST), serum albumin, serum bilirubin, prothrombin time and international normalized ratio (INR) were measured before surgery and at 1, 3, and 6 days after surgery.

Results
Transaminase levels, which were comparable in both groups, peaked between the first and the third postoperative days. Peak alanine aminotransferase was 224.27±29.7 and 318.20±52.5 U/L in the group A and group B, respectively (P &lt; 0.001). Peak aspartate aminotransferase was 265.60±22.3 U/L in group A and 349.27±56.1 U/L in group B (P &lt; 0.001). Albumin levels at day one showed no significant differences between both groups but at days 3 and 6, group A showed significantly higher albumin levels than group B. Other liver function tests including serum albumin, total and direct bilirubin, PT and INR showed lower values in propofol/dexmedetomidine group.

Conclusion
The main finding of this study is that propofol/dexmedetomidine as a technique for maintenance of anesthesia resulted in less hepatocellular injury and better hepatic functions than desflurane in patients undergoing partial hepatectomy during the first 6 postoperative days.

Comparison of Two Different Dexmedetomidine Doses and Their Effect on the Duration of Spinal Anesthesia in Lower Limb Amputation Surgeries
Authors: El-Nasr Mohamed Gihan Seif , Abdel-Malek Fady Adib , El- Khouly Ahmed Tarek , El-Sayed Waleed Ibrahim 
Published: July 2024

Abstract

Background
Spinal anesthesia is a very common technique used in lower limb surgeries. Dexmedetomidine is a highly selective α2-adrenergic agonist which has been used as pre-medication and as an adjuvant to general anesthesia. It is found that injection of dexmedetomidine intrathecally prolongs both sensory and motor block and has antinociceptive action for both visceral and somatic pain by depressing the release of nociceptive C fibers transmission and hyperpolarization of post synaptic dorsal horn cells.

Objective
To compare the effect of addition of different doses of dexmedetomidine to bupivacaine on the duration of spinal anesthesia, quality of block, intraoperative and postoperative complications and postoperative analgesia in patients undergoing lower limb amputation surgeries.

Methods
This prospective double blind randomized controlled clinical trial was done on sixty six adult patients of both sexes, aging from 21 to 60 years old, ASA I and II presented to Ain Shams University Hospitals for lower limb amputation surgeries were involved in this study during the period from July 2021 till May 2022.

Results
The addition of dexmedetomidine to bupivacaine in spinal anesthesia significantly prolonged both sensory and motor blockades duration compared with bupivacaine alone. It was significantly faster in group B (2.1 ± 0.124) compared with A and C groups (2.64 ± 0.34) and (4.72± 0.31) respectively and in group A compared with group C. They also prolonged the time of postoperative analgesia as evidenced by significantly longer time to first rescue analgesia Time to first call for rescue analgesia was significantly longer in group B (350 ± 45 mins) compared with A(287.41 ± 40.83 mins) and C(192 ± 42 mins) groups and in group B compared with group A. Also, there was significant difference in number of analgesic doses in group B compared to A and C groups and in group B compared to group A. Lower VAS scores with minimal adverse effects and hemodynamic stability. Comparing two different doses of dexmedetomidine showed that 15μg dexmedetomidine caused more prolongation of the spinal block duration and the time of postoperative analgesia than dexamethasone. It also decreased shivering during spinal anesthesia with only 4 patients compared to group A with 8 patients and group C with 9 patients.

Conclusion
5μg dexmedetomidine seems to be an attractive as an adjuvant to spinal bupivacaine in surgical procedures. It provided good quality of intraoperative analgesia, hemodynamically stable conditions, minimal side effects, and excellent quality of postoperative analgesia. Unfortunately, it had not any effect on incidence or severity of phantom pain and sensation in lower limb amputation surgery, but 15μg had better time of analgesia and longer time till the patient needed rescue analgesia with lower VAS score with no remarkable difference in the side effect as revealed.
