THE ANESTHETIC EFFECTS OF THE TRANSVERSUS ABDOMINIS PLANE BLOCK COMBINED WITH TCI-PROPOFOL IN GASTROSTOMY SURGERY
Main Article Content
Abstract
Aims: The analgesic efficacy and effects on respiratory, circulatory, and adverse outcomes of the Transversus Abdominis Plane (TAP) block with I.V TCI-propofol sedation are compared with general anesthesia with a laryngeal mask in gastrostomy surgery patients. Methods: In a randomized trial, 126 patients were divided into two groups: TAPB group (n = 63), receiving bilateral TAP blocks (0.33% ropivacaine at 3 mg/kg) combined with TCI-propofol at a target effect-site concentration (Ce) of 0.5–1 µg/ml and MASK group (n = 63) received general anesthesia with a laryngeal mask, induction with propofol, maintenance with desflurane, and fentanyl for intraoperative analgesia. Results: The TAP block was successful in 82.5% of cases, providing adequate analgesia in 93.7% and achieving successful anesthesia in 100% of patients. Intraoperative pain levels (SPI score) remained within acceptable limits in both groups. The TAPB group demonstrated more stable blood pressure than the MASK group, and no cases of respiratory depression were observed. Patient satisfaction with the anesthesia method was comparable between groups. Nausea and hiccups were observed in 4.7% of patients in the TAPB group, while 6.3% in the MASK group experienced laryngospasm. Conclusion: TAP block with TCI-propofol sedation offers effective analgesia and anesthesia in gastrostomy surgery, with stable respiratory and circulatory profiles and minimal adverse effects, especially suited for high-risk patients
