Transversus Abdominis Plane Block Versus Wound Infiltration of Local Anesthesia For Post Operative Analgesia

Abstract

Background: Since the concept of day care surgeries are getting more popular, surgeons and anesthesiologists are trying their best to provide adequate post operative analgesia. Infiltration of surgical wound with local anesthetics has been a well established practice to take care of post operative pain and the TAP block has been recently popularized. Aim: To compare the efficacy of TAP block with wound infiltration of local anesthesia for post operative pain. Material and Method: The study included total 50 patients grouped in two groups having 25 each. Group I received TAP block and group II received local infiltration of local anesthesia. The pain scores were measured in the two groups using VAS at 1 hour, 3 hours, 6 hours and 12 hours after surgery. Results: The TAP block group was shown to have statistically significant post operative analgesia even after 12 hours of surgery as compared to wound infiltration group; however the pain scores in both the groups were comparable till 6 hours of surgery. Conclusion: TAP block and wound infiltration of local anesthesia both provide significant post operative analgesia initially but the effects are more long lasting in TAP block.

The analgesic efficacy of transversus abdominis plane block vs. wound infiltration after inguinal and infra-umbilical hernia repairs

“…18,19 Table 1 presents the trial characteristics. The number of included patients ranged from 40 21 to 100. 24 Five studies included patients undergoing inguinal hernia repair only, [18][19][20]22,24 while two included patients undergoing inguinal or infra-umbilical hernia repair, 21,23 without presenting data for surgical subgroups.…”

“…22 TAP block and wound infiltration were performed at the beginning of surgery in three studies 18,19,22 and at the end in four studies. 20,21,23,24 All authors injected a single bolus of long-acting local anaesthetic and used the same concentration of local anaesthetic for both groups, except one study that injected bupivacaine 0.25% for the TAP block and bupi-vacaine 0.5% for wound infiltration. 22 No study used perineural or intravenous adjuncts.…”

“…24 Five studies included patients undergoing inguinal hernia repair only, [18][19][20]22,24 while two included patients undergoing inguinal or infra-umbilical hernia repair, 21,23 without presenting data for surgical subgroups. Inguinal or infra-umbilical hernia repair was performed with an open surgical approach in five studies 18,20,21,23,24 and with laparoscopy in two studies. 19,22 All interventions were performed under general anaesthesia and maintained with inhalation agents.…”

“…Of the 1123 trials identified from the literature search, seven met the inclusion criteria, [18][19][20][21][22][23][24] including a total of 420 patients (Supplementary Fig. 1, http://links.lww.…”

Ultrasound-guided transversus abdominis plane block: What are the benefits of adding dexmedetomidine to ropivacaine?

“…comparing TAP block versus wound infiltration of local anesthesia for postoperative analgesia concluded that TAP block and wound infiltration of local anesthesia both provide significant postoperative analgesia initially but the effects are more long-lasting in TAP block. [ 11 ]…”
