Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Patient will have usual appendectomy surgery with an injection of local or saline at incision site either before or after the incision at random.

The clinical hypothesis of this trial is that pediatric patients who undergo a local anesthetic pre-incisional and/or post-incisional will reduce the amount of postoperative pain and therefore reduce the amount of analgesics required to keep the patient satisfied.

Primary: To determine if local anesthetic reduces postoperative pain. Secondary: To assess the timing of local anesthetic injection affects postoperative pain.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

This is a prospective randomized-controlled pilot study of 100 pediatric subjects, recruited through Phoenix Children's Hospital and Pediatric Surgeons of Phoenix, who will undergo a laparoscopic appendectomy (LA) for acute non-perforated appendicitis. The reviewer and subject will be blind to the treatment to help prevent bias. The subjects will be randomized by envelope using a random number generator, and the infiltrated solution will be given to the surgeon by the pharmacy.

The subjects will be approached preoperatively and will be divided into three groups: pre-incisional injection of local anesthetic, post-incisional injection of local anesthetic, and (pre or post) injection of saline as the control.

All patients will have a standard 3 port laparoscopic appendectomy, port placement, port and instrument type, and operative technique will be determined by the surgeon's usual practice.

On induction, the following protocol will be utilized: a 2 mg/kg bolus of propofol, 1.5 mg/kg of lidocaine, 0.1 mg/kg of morphine, and 0.6 mg/kg of rocuronium. A standardized anesthetic, using a mixture of sevoflurane in oxygen and air, will be utilized. Once the appendectomy is complete, a single dose of 0.5 mg/kg of ketorolac will be given prior to extubation. A total of 0.5 mL/kg of 0.25% Bupivicaine or saline, up to a maximum of 30 cc, will be injected using a 22g needle. Pre-incision: local will be to be given intradermally and onto the peritoneum under direct vision; post-closure local will be injected intradermally after closure.

The subjects will be assessed for postoperative pain immediately upon wakening, and then 1, 2, 4, 8, 12, and 24 hours after the LA procedure by the bedside nurse by using the VAS and by measuring the total amount of opioid use.
