Brief summary
The parietal component is incisional pain experienced at the port sites and visceral component is deep intra-abdominal pain related to diaphragmatic irritation caused by pnemoperitoneum and postcholecystectomy wound. Shoulder tip pain is presumably referred pain related to distension of diaphragm caused by pneumoperitoneum and resultant phrenic nerve neuropraxia.The aim of our prospective, randomized, double-blind study was to evaluate the intensity of visceral, parietal and shoulder tip pain, and to determine the efficacy of peritrocal injection and intraperitoneal instillation of ropivacaine on each pain.
Interventions
arm 1:both infiltration at the port site and intraperitoneal instillation: 20ml of a solution containing ropivacaine (2 mg/ml) was infiltrated at the port site before insertion of trocar and 100 ml of ropivacaine solution (2 mg/kg) was infused intraperitoneally immediately after the creation of the pneumoperitoneum and 10 min before the beginning of surgery.. arm 2: intraperitoneal instillation: 20ml normal saline was infiltrated at the port site before insertion of trocar, and 100 ml of ropivacaine solution (2 mg/kg) was infused intraperitoneally immediately after the creation of the pneumoperitoneum and 10 min before the beginning of surgery.. arm 3: infiltration at the port site:20ml of a solution containing ropivacaine (2 mg/ml) was infiltrated at the port site before insertion of trocar and 100 ml of normal saline solution was infused intraperitoneally immediately after the creation of the pneumoperitoneum and 10 min before the beginning of surgery..
