Ultrasound Guided Retrolaminar Block Versus Thoracic Epidural Analgesia Following Laparoscopic Cholecystectomy
Ultrasound Guided Retrolaminar Block Versus Thoracic Epidural Analgesia Following Laparoscopic Cholecystectomy
The aim of this study is to evaluate analgesic effect of ultrasound-guided retrolaminar block
 vs ultrasound-guided thoracic epidural analgesia in pain control following laparoscopic
 cholecystectomy.
To study the difference between the effects of ultrasound-guided bilateral retrolaminar block
 and ultrasound-guided thoracic epidural analgesia on pain control following laparoscopic
 cholecystectomy. To relief pain and improve satisfaction in patients undergoing laparoscopic
 cholecystectomy at Zagazig university hospitals.
