Abstract
Nerve root or myofascial irritation at the abdominal wall is a common cause of pain following surgeries such as cesarean section, cholecystectomy, prostatectomy, hysterectomy and transplant surgery.
Spinal is used as an anesthetic technique and systemic opioid analgesia techniques are often used to manage pain after abdominal surgeries and appropriate pain management is necessary for optimizing clinical outcomes and patients’ satisfaction. However, systematic opioids complications such as nausea, vomiting and respiratory depressions are often associated with opioid use. As a result, investigation of alternative analgesia regimens to enhance effectiveness in postoperative pain management while improving the safety profile has emerged as a significant field of inquire.
The aim of this study is to test the efficacy of ultrasound guided transverse abdominis plane versus ultrasound guided rectus sheath block as regards its efficacy, hemodynamic stability, onset of post-operative pain, amount of post-operative narcotics used.
In the current study eighty patients who received spinal anesthesia were included. Patients were divided randomly into two groups, each group consisted of 40 patients.
group A: Patients in this group received bilateral ultrasound guided transverse abdominis plane block at the end of surgery.
group B: Patients in this group received bilateral ultrasound guided rectus sheath block at the end of surgery.
As regard the analgesic parameters recorded; in the current study, the visual analog scale was significantly lower in group A (transverse abdominis plane block) when compared with that of group B (Rectus sheath block) and showed significant difference between both groups at 6, 8 and 10 hrs postoperatively.
In the current study, time to rescue analgesia, there was statistically highly significant longer time to 1st rescue analgesic in group A (transverse abdominis plane block) with compared to that of group B (rectus sheath block).
Also, total analgesic consumption was highly statistically significant difference in the mean total analgesic consumption in between group A and group B.
