Background: The peritoneal wound is frequently neglected during laparotomy. The preperitoneal local anesthetics and many adjuvants were effective for postcesarean analgesia. Analgesia may involve somatic and autonomic components. The preperitoneal bupivacaine and the promising adjuvants dexamethasone or dexmedetomidine were compared in this study.
Patients And Methods: Sixty patients subjected to a cesarean section (CS) under general anesthesia divided into two groups using a bolus of preperitoneal bupivacaine 0.7 mg/kg with either 1ug/kg dexmedetomidine (Group P) or 8 mg dexamethasone (Group D). The time to the first analgesic request was the primary outcome.
Results: There was a significantly prolonged time to the first analgesic request in the Group P than the Group D and less required preperitoneal injections in the Group P, also pain assessed by Numerical Rating Scale (NRS) was lower in the Group P than the Group D after 6 h postoperatively up to 24 h.
Conclusions: Dexmedetomidine provided better analgesia than dexamethasone as an adjuvant to preperitoneal bupivacaine post-CS.

The effect of dexamethasone and bupivacaine on postoperative pain and nausea and vomiting by preperitoneal nerve blocking in laparoscopic cholecystectomy: a randomized clinical trial.

Background: This study aims to examine the effects of preperitoneal administration of dexamethasone and bupivacaine surrounding laparoscopic trocars on postoperative pain (POP) and nausea and vomiting (PONV) in patients undergoing laparoscopic cholecystectomy (LC).
Method: In this randomized triple-blinded trial with a 1:1 randomization ratio, 104 patients with chronic cholecystitis were candidates for elective LC. A total of 40 mg (8 ml) of bupivacaine was mixed with 8 mg (2 ml) of dexamethasone or normal saline.

The purpose of this paper is to evaluate the safety and efficacy of continuous preperitoneal wound infiltration using bupivacaine after abdominal laparotomy in relation to plasma bupivacaine concentration and visual analog scale. Our study was performed on 60 adult patients with digestive cancer, operated at laparotomy, and randomized into two groups: bupivacaine and saline groups. The wound infiltration was through a multiperforated catheter along the scar.

Background: Modified thoracoabdominal nerve block through perichondrial approach is a novel fascial plane block and provides abdominal analgesia by blocking thoracoabdominal nerves. Our primary aim was to evaluate the efficacy of M-TAPA on quality of recovery and pain scores in patients who underwent laparoscopic inguinal hernia repair surgery (Trans Abdominal Pre-Peritoneal approach ‒ TAPP).
Methods: Patients with American Society of Anesthesiologists (ASA) physical status I-II aged between 18 and 65 years scheduled for elective TAPP under general anesthesia were enrolled in the study.

Purpose: While it is widely accepted that laparoscopic total extraperitoneal (TEP) inguinal herniorrhaphy has decreased post-operative pain, there are conflicting data as to whether instillation of local anesthetic into the preperitoneal space improves post-operative pain in these patients. We designed a prospective study to evaluate this. Secondary outcomes include time spent in the PACU, need for narcotic pain medication, and total amount of narcotics required postoperatively.

Objective: Given the role of celiac plexus block (CPB) in the management of chronic pain, we sought to investigate the utility of CPB in the control of postoperative pain in major hepato-pancreato-biliary surgeries.
Summary Background Data: CPB has been in practice for decades for the management of upper abdominal visceral pain, especially in cancer patients. Typically, in this group of patients with chronic pain, a neurolytic agent is injected to cause irreversible neural damage to achieve pain control.
