Symptomatic cholelithiasis in pediatric patients should be dealt with cholecystectomy. Due to its minimally invasive nature, laparoscopic approach is better than conventional open approach. Although safety of spinal anesthesia (SA) in adult laparoscopic surgeries including cholecystectomy is well established, its use in pediatric laparoscopic surgeries is extremely limited with only a few studies being published till date. Here, we report a case of laparoscopic cholecystectomy (LC) in a 5-year-old child which was successfully managed with SA. This may be the very first case report of pediatric LC under SA.
Background: Although various adjuvants have been added to local anesthetic agents to potentiate its effect, dexmedetomidine is a relatively new drug with only a fewer studies.
Aims and Objectives: The present study has been conducted to compare the efficacy of intrathecal hyperbaric bupivacaine alone with dexmedetomidine of two different doses as adjuvants in spinal anesthesia for the lower abdominal surgery.
Materials and Methods: This was a double-blinded, randomized, and controlled trial. Total 120 patients of American Society of Anesthesiologists physical status I and II, 70 male and 50 female, aged between 20 and 60 years, were randomized into three groups receiving 15 mg 0.5% hyperbaric bupivacaine with normal saline, 4 μg (microgram) dexmedetomidine, and 2 μg dexmedetomidine, respectively, administered intrathecally.
Results: There was significant difference among all three groups with regard to the onset of sensory block and time to reach the highest level of sensory block. Time to reach T10 dermatome, time to reach Bromage 3 motor block, the mean regression time to S1 dermatome level, the mean regression time to reach Bromage 0, and time to first requirement of rescue analgesia – all these variables showed significance when 4 μg dexmedetomidine additive group was compared with 2 μg dexmedetomidine additive group and bupivacaine alone group.
Conclusion: In our double-blinded, randomized, and controlled trial, 4 μg intrathecal dexmedetomidine coadministered with 0.5% hyperbaric bupivacaine showed superior efficacy. Further, larger trials are needed to confirm our findings.
Background: Direct laryngoscopy and endotracheal intubation elicit hemodynamic pressor responses which may be hazardous in high risk patients. Fentanyl, a low cost synthetic opioid, when used judiciously, may be a good option to attenuate this stress response.
Aims and Objectives: The present study has been conducted to compare the efficacy of three different doses of intravenous fentanyl in attenuation of hemodynamic pressor response to laryngoscopy and endotracheal intubation in elective surgery under general anesthesia.
Materials and Methods: It was a double-blinded randomized controlled trial. A total of 90 patients of American Society of Anesthesiologists physical status I and II, 55 male and 35 female, aged between 20 and 55 years, were randomized into three groups receiving 2, 3, and 4 μg/kg of injection fentanyl, respectively, administered intravenously 5 min before direct laryngoscopy and endotracheal intubation.
Results: There were significant differences in hemodynamic variables among all three groups at 1, 3, 5, and 10 min after endotracheal intubation. Just after endotracheal intubation; heart rate, mean arterial pressure, and diastolic arterial pressure – all these variables showed significance between 3 μg/kg and 4 μg/kg groups only. Incidence of nausea/vomiting showed statistical significance between 2 μg/kg and 4 μg/kg groups only.
Conclusion: In our double-blinded randomized controlled trial, 4 μg/kg of injection fentanyl administered 5 min before laryngoscopy and intubation, has showed superior efficacy in suppressing hemodynamic stress responses associated with it. Further, larger trials are needed to confirm our findings.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
