About this study
Official title: Medical Doctor of Anesthesiology and Reanimation
To compare the effect of M-TAPA block and port-site local anesthetic infiltration on postoperative pain in pediatric laparoscopic appendectomies. The main questions it aims to answer are:
- Is M-TAPA block more effective in reducing pain?
- How M-TAPA block affects the use of rescue analgesics in the postoperative period? Participants will have the same anaesthetic agents during surgery, before extubation they will have same analgesic agent for postoperative pain. Participants in the M-TAPA group will undergo USG-guided M-TAPA block bilaterally with % 0.025 Bupivacaine max dose of 2 mg/kg by the same experienced anesthesiologist before extubation. Participants in the LAI group will be administered 0.025% Bupivacaine at a maximum dose of 2mg/kg divided equally and administered by the surgeon at 3 port entry sites before the patient is extubated.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
M-TAPA BlockProcedure or surgery
M-TAPA Block; The block will be done by the same experienced anesthesiologist by using ultrasound(USG) after the surgical intervention is completed.The external oblique, internal oblique, and transversus abdominis muscles were shown on the costochondral angle in the sagittal plane at the 10th costal margin by using a high-frequency linear probe. Bilaterally in the midclavicular line at the level of the 10th rib (arcus costarum),0,5 ml/kg 0.25% Bupivacaine (maximum dose 2mg/kg) was administered to between the upper fascia of the transversus abdominis muscle and the lower fascia of the costochondral tissue.
Local anesthetic infltration to port sitesProcedure or surgery
Local anesthetic infiltration to port sites; The surgeon infiltrated 0.5 ml/kg of 0.25% Bupivacaine (maximum dose of 2mg/kg) in the skin, subcutaneous tissue, and muscle fascia at each of the three laparoscopic port areas at the end of the surgery.
| Study group | Role | What they receive |
|---|---|---|
| M-TAPA group | Experimental | The group to be administered 0.025% Bupivacaine by the anesthesiologist bilaterally in M-TAPA block with a maximum dose of 2 mg/kg before extubation. Receives: Procedure: M-TAPA Block |
| LAİ group | Active comparator | The group to be divided and administered 0.025% Bupivacaine with a maximum dose of 2 mg/kg by the surgeon to 3 port entry sites before extubation Receives: Procedure: Local anesthetic infltration to port sites |
What is being measured
The primary outcome is the main question the study is designed to answer.
Total number of rescue analgesic applications
During the first 24 hours postoperatively, patients' pain will be monitored by Visual Analogue Scale (VAS) scoring. Paracetamol will be given intravenously at a dose of 10mg/kg if the VAS is greater than 4 in pain assessment in the postoperative period. We will record the number of times the patient received rescue analgesics over a 24-hour period.
Measured: Postoperative first 24 hours
Secondary outcomes (1)
Comparison of pain between 2 groups in the postoperative period
The Visual Analogue Scale (VAS) scores were recorded postoperatively at 0 (PACU), 1, 4, 6, 12, and 24 h.
Visual Analogue Scale (VAS)
Scale vertical or horizontal from a 10 cm long line drawn as is formed. At the two ends of this line are the two end descriptor word (0 = "no pain at all", 10 = worst/unbearable pain").The patient is asked to place a mark in the appropriate place for the intensity of the pain.
Measured: Postoperative first 24 hours
