Laparoscopic Bariatric Surgery, Nausea and Vomiting

Brief summary

Purpose: To explore and compare Ultrasound-Guided Transversus Abdominis Plane Block on Postoperative nausea and vomiting and Early Outcome After Laparoscopic Bariatric Surgery To evaluate and examine TAPB can reduce the application of intraoperative and postoperative opioids and the duration of analgesia

Detailed description

Poor postoperative nausea and vomiting control is a leading factor that hinders the physical rehabilitation, and causes acute cognitive impairment and chronic pain syndrome. Recently, the multimodal analgesia strategies to minimise opioid-related side effects are highly desirable in open surgical procedures. The transversus abdominis plane block is a novel technique involving injection of local anaesthetic between the internal oblique and the transversus abdominis muscles of the abdominal wall. Although ropivacaine is most commonly used for this technique, the analgesic duration remains not dissatisfied. Herein, we will evaluate the efficacy of ultrasound-guided transversus abdominis plane (USG-TAP) block with ropivacaine in Laparoscopic Bariatric Surgery

Interventions

DRUGRopivacaine

Before the induction of anesthesia, ropivacaine is used for bilateral transversus abdominis plane block in a volume of 20 mL of each side

Design outcomes

Primary

MeasureTime frameDescription
Postoperative nausea and vomiting72 hours after surgeryPostoperative nausea and vomiting

Secondary

MeasureTime frameDescription
Cumulative Sufentanyl Consumption24 hours after surgeryEach patient was administered analgesics using a PCA pump containing sufentanil (100μg) in normal saline at a total volume of 100 ml after leaving PACU. This device was set to deliver a basal infusion of 2 ml/h and bolus doses of 0.5 ml with a 15-min lockout period. Sufentanyl cumulative consumption is recorded 24 hours postoperatively
Time of First Postoperative Analgesic Requirement1 hour after surgeryFirst postoperative pain (NRS≥4) is initially controlled by titration of sufentanyl
Occurrence of Side Effects24 hours after surgeryOccurrence of side effects: nausea, vomiting, dizziness, headache, shivering, pruritus
Total Dose of First Postoperative Analgesic Requirement1 hour after surgeryFirst postoperative pain (NRS≥4) is initially controlled by titration of sufentanyl.
