Study summary

Effectiveness of the TAP block compared to wound infiltration in controlling pain after laparoscopic appendectomy in children

Read the detailed description

Laparoscopic appendectomy is one of the main emergency surgical procedures performed in children.

The available local anesthesia techniques include wound infiltration or "wall" blocks such as the TAP (transversus abdominis plane) block.

The greater evidence on the adult population suggests that both techniques are valid for pain control in the immediate postoperative period, although wall blocks can guarantee a more prolonged analgesic effect over time.

The evidence on the pediatric population, on the other hand, is less strong and sometimes conflicting: therefore, the objective of our study is to verify the efficacy of TAP block compared to wound infiltration in the control of postoperative pain after appendectomy in pediatric patients.

Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.

Inclusion criteria

  • Patients aged between 3 and 16 years, candidates for laparoscopic appendectomy for suspected acute appendicitis.
  • Class I and II
  • signed by parents / legal guardians

Exclusion criteria

Exclusion Criteria:

  • severe obesity (> 95th percentile for age and weight)
  • perforated appendicitis
  • paralytic ileum
  • non-stabilized neuropathies
  • allergy to local anesthetics or analgesics used in the study protocol.
  • patients on chronic opiate treatment
  • need for perioperative hospitalization in intensive care with sedation and / or mechanical ventilation
Terms in these criteria, in plain language(3)

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.

ASA physical status

The anaesthetists’ scale of health before surgery: I is healthy, II has a mild illness that is under control, III a severe one, IV a severe illness that is a constant threat to life. V and VI are used for the critically ill and for organ donors.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

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.

Study arms

  • Experimental
    TAP block

    Bilateral ultrasound-guided single-shot TAP block with 0,15% levobupivacaine 0,75 mg/kg per side.

    Procedure: TAP Block · Procedure: General anesthesia · Drug: Postperative analgesia

  • Active comparator
    LIA - local wound infiltration

    Wound infiltration with 0,5% levobupivacaine 1.5 mg/kg

    Procedure: LIA local infiltration · Procedure: General anesthesia · Drug: Postperative analgesia

Interventions

  • ProcedureTAP Block

    At the end of surgery patients will receive bilateral ultrasound-guided single-shot TAP block: 0,15% levobupivacaine 0,75 mg/kg per side will be injected between internal oblique and transveralis fascia

  • ProcedureLIA local infiltration

    At the end of surgery 0,5% levobupivacaine 1.5 mg/kg, equally distributed between ports, injected in the skin and subcutaneous tissue during wound closure.

  • ProcedureGeneral anesthesia

    General anesthesia will be induced with fentanyl 1,5 mcg/kg, propofol 2 mg/kg, rocuronium 0,6 mg/kg; after intubation anesthesia will be mantained with sevoflurane (MAC 1). 30 minutes after induction will be administered paracetamol 15 mg/kg iv.

  • DrugPostperative analgesia

    During first 48 hours after surgery all patients wil receive paracetamol 15 mg/kg iv every 8 hours and ibuprofen 10 mg/kg orally (or through gastric tube) every 12 hours after surgery. In case of severe pain tramadol 0,5 mg/kg will be administered iv every 8 hours.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Mar 4, 2020, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
