Study summary

Laparoscopic cholecystectomy is a commonly performed operation in general surgery practice. Peripheral nerve block methods commonly used for analgesia after this operation are: transversus abdominis plane block (TAP) and trocar insertion sites local anesthetic infiltration anesthesia In this study, we aimed to compare these methods in terms of postoperative analgesia, nausea-vomiting and patient satisfaction

Read the detailed description

Patients will be randomly allocated by a computer generated random numbers list into three groups. After general anesthesia induction and intubation patients will receive analgesia according to group allocation. In group TAP (Group T) the transversus abdominis plane block will be commenced with ultrasound guidance while the patients is in the supine position with a subcostal approach using 20 mL 0.25% bupivacaine and 21 G block needle. In group infiltration anesthesia (Group I) the trocar insertion sites will be infiltrated with 20 mL 0.25% bupivacaine: 7 mL for the 10 mm trocar insertion sites and 3 mL for the 5 mm trocar insertion sites. The control group (Group C) will not receive any local anesthetic. All patients will receive rescue analgesia with intravenous patient controlled analgesia with tramadol (20 mg bolus dose and 20 minutes lockout time)

Postoperative pain will be assessed during resting and coughing with a Numeric Pain Scale (NRS) and nausea and vomiting with a Postoperative Nausea Vomiting Score at the postoperative 1, 3, 6, 12. and 24 hours. The amount of tramadol consumed in the postoperative period will be recorded. Patient satisfaction will be assessed with the Likert scale at postoperative 24 hours.

Terms in these criteria, in plain language(1)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

BMI (body mass index)

Weight in kilograms divided by height in metres squared. Example: 70 kg and 1.75 m gives 70 ÷ (1.75 × 1.75) ≈ 22.9.

What counts as overweight or obesity differs between countries (some use lower cut-offs), so go by the range the study states.

What researchers measure

Primary outcomes

  1. Postoperative analgesia

    Pain will be assessed with a 11 point numeric rating scale (0-10 whereas 0:no pain; 1-3: mild pain; 4-6: moderate pain and 7-10: severe pain)

    Time frame: Postoperative day 1

Secondary outcomes

  1. Postoperative nausea and vomiting (PONV)

    PONV will be assessed with a 5 point PONV intensity scale (1-4 whereas 1:absence of PONV; 2: nausea present, vomiting absent; 3 nausea present, vomiting once; 4: nausea present vomiting twice or more

    Time frame: Postoperative 1st hour, 3rd hour, 6th hour, 12th hour and 24th hour

  2. Patient satisfaction

    Satisfaction will be assessed with a 5 point Likert scale (0-4 whereas 0:definitely disagree; 1:slightly agree; 3: agree; 4: strongly agree)

    Time frame: Postoperative 24 th hour
