Description

In routine practice at our institution, anesthesia clinicians performing gynecologic laparoscopic procedures administer either modified thoracoabdominal nerve block through perichondrial approach (M-TAPA Block) alone or a combination of M-TAPA and external oblique muscle plane (EXOP) blocks, based solely on individual clinician preference. The researcher does not influence this decision. Among the eligible patients, those receiving either M-TAPA or M-TAPA + EXOP will be included and evaluated observationally. Block types other than these two will not be included.

All postoperative visits and clinical follow-ups are routinely conducted by the hospital's pain management team. The researcher does not intervene in these clinical processes and is only responsible for obtaining informed consent, recording demographic variables, documenting the type of block performed, administering the QoR-15 questionnaire, and evaluating sensory block distribution using the pinprick test.

Preoperative evaluation and necessary laboratory testing are carried out according to standard hospital practice by the attending anesthesiologist. The researcher obtains informed consent, records demographic data, and administers the preoperative QoR-15 questionnaire.

In the operating room, standard monitoring (non-invasive blood pressure, ECG, heart rate, and oxygen saturation) is applied, intravenous access is established, and crystalloid infusion is initiated. Anesthesia induction is performed using propofol, an opioid, and a neuromuscular blocking agent, followed by endotracheal intubation. General anesthesia is maintained with sevoflurane in an oxygen-air mixture. Laparoscopic surgery is performed with gradual CO₂ insufflation, maintaining intra-abdominal pressure below 12 mmHg.

For postoperative analgesia, all patients routinely receive 1 g intravenous paracetamol and 100 mg tramadol. After surgery, neuromuscular blockade is reversed and patients are transferred to the post-anesthesia care unit (PACU).

After surgery, patients are monitored in the PACU and transferred to the ward once their Aldrete score is ≥9. All patients receive 1 g intravenous paracetamol every 8 hours as per routine protocol. Postoperative pain is assessed by the pain team using the 0-10 Numeric Rating Scale (NRS).

Postoperative nausea and vomiting (PONV) are assessed and intravenous ondansetron 4 mg is administered for PONV ≥2. Patients without PONV are encouraged to mobilize early and resume oral intake. Discharge is permitted once symptoms resolve; however, all patients remain hospitalized for at least 24 hours.

As an additional study-related procedure, the researcher evaluates dermatomal spread using the pinprick test and administers the QoR-15 questionnaire at 24 hours.
