Effect of Dexmedetomidine on Haemodynamic Response to Pneumoperitoneum in Patients Undergoing Laparoscopic Cholecystectomy
Journal Title: Indian Journal of Anesthesia and Analgesia - Year 2019, Vol 6, Issue 1
Abstract
Background: As laparoscopic cholecystectomy is a routinely performed surgery, it is desirable to have a stable intraoperative haemodynamic status. This study is designed to evaluate the efficacy of single intravenous bolus dose of dexmedetomidine, given 10 minutes before induction of anesthesia to provide hemodynamic stability in patients undergoing laparoscopic cholecystectomy. Materials & Methods: A Double blind randomized controlled study was conducted in the department of Anaesthesiology, Manipal Hospital Bangalore, Patients undergoing elective laparoscopic cholecystectomy, under general anaesthesia for a period of one year from June 2013 to May 2014. Total 60 patients belonging to ASA physical status I and II, in the age group of 18 to 65 years scheduled for elective laparoscopic cholecystectomy surgery were selected for this study. The two groups, Dexmedetomidine and control, were comparable with respect to age, sex, weight and ASA physical status. Results: We observed lesser magnitude of variation in HR, SBP, DBP, MAP atinsufflation of pneumoperitoneum until 30 minutes post pneumoperitoneum in dexmedetomidine group compared to control group (p<0.05). During pneumoperitoneum the maximum SBP and MAP attained in dexmedetomidine group was lesser compared to control group (p<0.001). Dexmedetomidine group also had less number of episodes of increase in SBP and MAP of more than 20% of baseline. We also found that the requirement for more than 1% of isoflurane in control group was higher (73%) compared to dexmedetomidine group. The recovery time was found to be similar in both groups. Conclusion: In conclusion, dexmedetomidine at a dose of 1 μgkg-1 bolus given at induction of anesthesia over 10 minutes resulted in statistically significant hemodynamic stability during pneumoperitoneum in patients undergoing elective laparoscopic cholecystectomy surgeries.

Aim: The aim of this study is to evaluate the effect of the low doses of ketamine and midazolam with bupivacaine intrathecally in terms of duration of analgesia and haemodynamic parameters. Materials and Methods: This...
A Comparative Study Between Ultrasound and Peripheral Nerve Stimulator Guided Supraclavicular Brachial Plexus Block in Adult Patients for Elective Upper Limb Orthopaedic Surgeries
Background: There are many advantages of ultrasound guided supraclavicular brachial plexus block over the peripheral nerve stimulator guided supraclavicular brachial plexus block. Ultrasonography allows the operator to v...
Anaesthetic Management of High Risk Chronic Kidney Disease Patient for Continuous Ambulatory Peritoneal Dialysis Catheter Insertion with Omentectomy
A patient with Chronic Kidney Disease (CKD) having history of Ischaemic Heart Disease (IHD) and Interstitial Lung Disease (ILD) was planned for CAPD catheter insertion with omentectomy. Usually CKD patients requiring gen...
Comparision of High Dose Rocuronium with Succinylcholine for Intubation
Context: Succinylcholine has extremely rapid onset of action and its shorter duration of action make it the ideal muscle relaxant for rapid sequence intubation. Because of these adverse effects and risks associated with...
