Brief Summary
Laparoscopic cholecystectomy is associated with considerable postoperative pain and surgeon-administered local anesthetic infiltration is the standard practice for achieving post-operative analgesia. However, recent studies have shown that pediatric patients continue to experience significant pain during the first 24 hours. The investigators plan to conduct a prospective, double-blinded, randomized study where patients will be designated into either a test group receiving an ultrasound-guided transversus abdominis plane (TAP) and rectus sheath (RS) blocks with ropivacaine and peri-portal sterile saline or the control group that will receive ultrasound-guided TAP block with sterile saline and peri-portal infiltration of ropivacaine. The anesthesia team and surgical team will both be blinded as well as the research personal in the postoperative period. Patients age 5-17 and American Society of Anesthesiology status I and II undergoing laparoscopic cholecystectomy will be included. The study hypothesis is that ultrasound-guided peripheral nerve blocks, specifically single shot transversus abdominis plane and rectus sheath blocks, are superior to local wound infiltration during laparoscopic cholecystectomy for decreasing postoperative pain and pain related behavior and facilitating functional recovery.

Study Arms (2)
Abdominal Wall Block with Ropivacaine 0.2%
ACTIVE COMPARATORPatients will receive bilateral transversus abdominis plane and rectus sheath blocks via ultrasound guidance. A total of 1.0ml/kg distributed between the four blocks (0.4+0.4+0.1+0.1) of 0.2% Ropivacaine (max 50ml) will be injected, as a one time single shot injection, into the fours sites. Surgical infiltration of the four port sites will receive 0.4ml/kg of sterile saline.
Surgical Infiltration with Ropivacaine 0.5%
ACTIVE COMPARATORPatients will receive surgical infiltration of local anesthetic into the 4 laparoscopic port sites. A total of 0.4 ml/kg (0.1+0.1+0.1+0.1) of 0.5% Ropivacaine, divided between the four port sites (max 20 ml), will be used. A total of 1ml/kg, divided between the TAP (0.4ml/kg on each side) and RS (0.1ml/kg on each side), of sterile saline will be used for the nerve blocks.
Interventions
bilateral TAP and RS blocks.
distributed between the 4 laparoscopic port sites.
Placebo injection
Ropivacaine 0.2% 1.0 ml/kg total in divided doses for bilateral TAP and RS blocks.
For nerve localization
Ropivacaine 0.5% 0.4 ml/kg total in divided doses distributed between the 4 laparoscopic port sites
