The effect of TAP Block on Pulmonary function in patients undergoing Laparosocopic Cholecystectomy
Department of Anesthesiology and Pain Medicine, College of Medicine, Chung-Ang University, Chung-Ang University Hospital, Seoul, Republic of Korea
Background: Transversus abdominis plane block (TAPB) is commonly used for postoperative pain control after laparoscopic cholecystectomy. However, there are few studies on the effect of TAPB on respiratory function. The main goal of our study is to elucidate the effect of ultrasound-guided bilateral TAPB on pulmonary function preservation and analgesia after laparoscopic cholecystectomy.
Methods: Fifty-eight patients who underwent laparoscopic cholecystectomy were enrolled. Fifty-three of them were randomized to group T (n=27) and group C (n=26). Group T received ultrasound-guided bilateral TAPB with 40 ml of 0.375% ropivacaine, and group C with 40 ml of 0.9% normal saline, respectively. Visual analog scale (VAS), patient-controlled anesthesia (PCA) consumption, forced expiratory volume in 1 second (FEV1), forced vital capacity (FVC), peak expiratory eratively.
Result: VAS scores of group T were statistically significantly lower than group C at 1h and 8h postoperatively. PCA consumption was significantly lower in group T than group C at all postoperative measurement points. Group T showed significantly lower modified Borg scales compared to group C, at 1 hour and 8 hours postoperatively. FEV1, PEF, FEV1/FVC of group T were more preserved than group C at 1 hour postoperatively.
Conclusion: Ultrasound-guided TAPB is effective on respiratory function preservation and pain control after laparoscopic cholecystectomy. So, ultrasound-guided TAPB could be a great option for multimodal analgesia, preservation of pulmonary function, prevention of pulmonary complications including atelectasis, and promotion of postoperative recovery after laparoscopic cholecystectomy.
