comparison of intraoperative local anesthetic applications in postoperative pain management in laparoscopic cholecystectomy patients

Conditions: Postoperative Pain

Summary: since 1987, laparoscopic cholecystectomy has become the standard procedure for gallbladder stones and lesions. complications due to improvements in laparoscopy and increased surgical experience have decreased day by day, but there is still a problem in terms of postoperative pain management. several pain management procedures have been tried to combat pain after laparoscopic cholecystectomy. the aim of this study is to decrease the length of hospital stay, to increase the comfort of the patient and to reduce the cost of treatment. local anesthetic injection to port locations, intraperitoneal periportal local anesthetic injection ,transversus abdominis plane blok and without any local anesthetic application to the control group compared to the group's analgesic efficiency and to reduce the amount of analgesics needed, shorten the length of hospital stay and improve patient comfort.

laparoscopic cholecystectomy procedure will be performed in patients older than 18 years of age for the diagnosis of cholelithiasis. laparoscopic cholecystectomy procedure will be performed.4 patients group will be formed power: 0.80 and alpha: :0.05 the minimum number of samples determined for each group is n: 34 for each group. it will be determined. in our clinic, local anesthetic injections are performed routinely to the trocar areas in laparoscopic cholecystectomy operations. after endotracheal intubation at the beginning of the operation, after appropriate skin staining and sterile dressing, transversus abdominis plane block (10 cc / 10 cc, 0.5% bupivacaine to the right and left transversus abdominis muscle regions) will be applied. to the second group local anesthetic injection (6 cc to subxiphoid and infraumbilical trocar sites, 4 cc instead of 2 cc, 0.5% bupivacaine solution) to be applied, in the third group intraperitoneal direct vision of the gallbladder area-periportal area under the direct injection of local anesthetic spraying process (percutaneous method injected into the periportal area 1: 1 diluted with 20 cc saline, 20 cc 0.5% bupivacaine solution total 40 cc spraying will be applied. the fourth group will be the control group and any of these methods will not be applied, the operation time and peroperative complications (pouch perforation etc.) will be recorded. paracetamol 1 g + 1 mg / kg tramadol iv will be applied to all four groups as standard before extubation. visual analogue scale (vas) will be applied to all patients in the postoperative period. if vas\> 3 is still present, a dose of 1 mg / kg tramadol will be administered. tenoxicam 1x1 iv will be applied to the patients on the 12th hour. all patients were postoperative; 1,2,4,6,12,24. vas scores , patient satisfaction (0: never satisfied, 5: very satisfied) will be recorded. the group of patients will be determined according to the order of surgery. pain scores of the patients will be performed by a physician who is not in the operation who does not know which group is taken. the patients included in the group will not be known to the patient by the pain scoring system and the study will be done as double blind. patients will be randomized with this method.

Eligibility criteria:
inclusion criteria: * patients over 18 years of age who were admitted to the general surgery department with the diagnosis of cholelithiasis exclusion criteria: * patients who need to undergo peroperative open cholecystectomy procedure. * patients with local anesthetic or nsaid allergy * patients in pregnancy * patients who are breastfeeding * patients with connective tissue disease * patients with malignancy in postoperative gallbladder pathological examination and patients with any malignancy diagnosis * patients with renal impairment, where the effect of using marcain is unknown * cardiac disease * patients with hepatic impairment
