Comparison of post-operative analgesic efficacy of bupivacaine and ropivacaine using ultrasound guided oblique subcostal transverse abdominis plane block in open cholecystectomy under general anaesthesia
Journal Title: Medpulse International Journal of Anesthesiology - Year 2018, Vol 6, Issue 3
Abstract
Background: Cholecystectomy involves upper abdominal incision with considerable postoperative pain. Adequate postoperative analgesia has to be provided to prevent major pulmonary complications in the postoperative period. Ultrasound guided oblique subcostal Transverse abdominis plane block has been extensively used to provide adequate analgesia without haemodynamic complications. Aim: To compare the post operative analgesic efficacy of Inj.Bupivacaine 0.25% and Inj.Ropivacaine 0.2% in Ultrasound guided Bilateral Oblique Subcostal Transverse Abdominis Plane block for patients undergoing open cholecystectomy under general anaesthesia. Materials and Methods: The study was done on 60 patients who underwent bilateral oblique subcostal Transverse abdominis plane block for open cholecystectomy surgeries under general anaesthesia. Group A: 30 patients given Inj.Bupivacaine 0.25%, 40 ml (20ml on each side). Group B: 30 patients given Inj.Ropivacaine 0.2%, 40 ml (20ml on each side). Results: The mean visual analog score was less in group A when compared to group B from 30 minutes to 8 hours time intervals, which also has statistical significance. The mean duration of analgesia was longer in group A than group B. Both groups had significant reduction in opioid usage for alleviationg postoperative pain.Both the group had stable intraoperative and postoperative hemodynamics when mean HR, SBP, DBP and MAP were monitored. Conclusion: It is concluded that postoperative analgesia wih Inj.Bupivacaine 0.25% is more effective when compared to Inj.Ropivacaine 0.2% in prolonging the duration of Ultrasound guided Oblique subcostal transverse abdominis block. Intraoperative and Postoperative hemodynamics were maintained well in both the groups.

Correlation between arterial and end tidal carbon dioxide partial pressure during laparoscopic surgeries
Background: End-tidal carbon dioxide pressure (etCO2) monitoring is used as an indirect measure of arterial carbon dioxide partial pressure (PaCO2). To prevent hypercapnia, close intraoperative monitoring of etCO2 or PaC...
Comparison between intravenous dexmedetomidine and esmolol for induced hypotension during functional endoscopic sinus surgery and modified radical mastoidectomy
Aim: Bleeding is one of the major problems during surgery which reduces operative field visibility and recognition of anatomical landmarks becomes quite difficult. We aim to compare Dexmedetomidine and esmolol for contro...
Comparison of anaesthetic efficacy of nalbuphine and dexmedetomidine as an adjuvant to ropivacaine and lignocaine in supraclavicular block for upper limb surgeries
Background: Brachial plexus block provides an useful alternative to general anaesthesia for upper limb surgeries. The block characteristics of dexmedetomidine and nalbuphine as adjuvants to ropivacaine, a newly emerging...
Comparison of dexmeditomidine and magnesium sulfate as adjuvants to lidocaine for intravenous regional anaesthesia for prolongation of duration of analgesia
Background and Objectives: Intravenous regional anaesthesia (IVRA) is a very effective block for forearm and hand surgeries, but its effectiveness is limited by its short duration of action. Dexmeditomidine and magnesium...
Efficacy of caudal epidural clonidine against fentanyl in prolonging the post-operative analgesia along with Bupivacaine
Background: Aim of study was to evaluate the efficacy of caudal epidural Bupivacaine plus Clonidine to that of Bupivacaine plus Fentanyl in prolonging the post-operative analgesia. Materials and Methods: Study was conduc...
