Study summary

The goal of this clinical trial is to determine the safety and efficacy of combined intraperitoneal local anesthetic instillation and port-site infiltration using lidocaine and bupivacaine in adults aged 18 to 60 undergoing elective laparoscopic abdominal surgeries (such as laparoscopic cholecystectomy, appendectomy, or hernia repair). The main questions it aims to answer are: Does combined intraperitoneal local anesthetic instillation and port-site infiltration reduce immediate and early (up to 4 hours) postoperative pain scores? Does this intervention reduce the early need for additional postoperative analgesics and shorten the length of hospital stay? Researchers will compare the treatment group receiving lidocaine (2%) and bupivacaine (0.5%) by intraperitoneal instillation and port-site infiltration with a control group receiving normal saline by the corresponding routes to determine whether the local anesthetic intervention reduces postoperative pain and analgesic requirements. Participants will undergo scheduled elective laparoscopic abdominal surgery and receive either the local anesthetic intervention or normal saline during the surgical procedure. Pain will be assessed using the Visual Analog Scale (VAS) immediately after surgery in the recovery room and again at 2 and 4 hours after surgery. Analgesic needs will be monitored and documented, and total hospital stay will be recorded.

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

  • Adults aged 18 to 60 years.
  • Scheduled for laparoscopic abdominal surgery (e.g., laparoscopic cholecystectomy, laparoscopic appendectomy, or laparoscopic hernia repair).
  • (ASA) physical status I or II.
  • No history of chronic pain, opioid dependence, or severe medical comorbidities.
  • Able and willing to provide written .

Exclusion criteria

Exclusion Criteria:

  • Conversion from laparoscopic to open surgery.
  • Acute cholecystitis, gangrene, or empyema of the gallbladder.
  • Oncologic or extensive laparoscopic procedures expected to have a prolonged operative time.
  • Known allergy or to lidocaine, bupivacaine, or other local anesthetic agents.
  • Diabetes mellitus.
  • Current systemic use.
  • Pregnancy.
  • Cardiac, pulmonary, hepatic, or renal disorders.
  • History of opioid use or opioid dependence.
Terms in these criteria, in plain language(4)

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.

Hypersensitivity

An allergy, or another reaction of the immune system, to a substance. “Hypersensitivity to the study drug” means a known allergic reaction to it — not every side effect a medicine can have.

Corticosteroids (steroids)

Anti-inflammatory medicines such as prednisone, prednisolone and dexamethasone — not the anabolic steroids used for muscle.

Studies differ in what they allow: check which steroid medicines, routes (tablets, injections, creams, inhalers, eye drops) and doses this study accepts.

Study arms

  • Active comparator
    Local Anesthetic Group

    Participants in this arm will receive a total of 20 mL of study solution prepared by combining 10 mL of 2% lidocaine with 10 mL of 0.5% bupivacaine. The resulting 20-mL mixture will be divided equally between the intraperitoneal and port-site routes: 10 mL will be instilled intraperitoneally over the surgical bed, while the remaining 10 mL will be equally distributed among the trocar wounds for port-site infiltration.

    Participants in this arm will receive a total of 20 mL of normal saline, divided equally between intraperitoneal instillation and port-site infiltration: 10 mL will instilled intraperitoneally over the surgical bed, while the remaining 10 mL will equally distributed among the trocar wounds.

What researchers measure

Primary outcomes

  1. Need for rescue opioid analgesia

    Number of participants requiring rescue opioid analgesia for postoperative pain.

    Time frame: Immediately after surgery, 2 hours after surgery, and 4 hours after surgery

Secondary outcomes

  1. Postoperative pain intensity

    Postoperative pain intensity assessed using the Visual Analog Scale (VAS), ranging from 0 to 10, with higher scores indicating greater pain intensity.

    Time frame: Immediately after surgery, 2 hours after surgery, and 4 hours after surgery

  2. Length of hospital stay

    Duration of hospitalization, measured from admission to discharge.

    Time frame: From admission until hospital discharge (up to 1 week)

  3. Surgery duration

    Duration of surgery measured in minutes from anesthesia induction until completion of wound dressing.

    Time frame: During surgery
