Filter by:The increase in stress hormone level and hyperventilation caused by the postoperative pain may contribute to the development of hypokalemia during postoperative period. Therefore, if the postoperative pain is well controlled by the IV-PCA,the plasma potassium level during the postoperative period may be not affected by stress response. The researchers tried to investigate the effect of IV-PCA on potassium regulation during the postoperative period.
It is demonstrated that expiratory flow limitation and as a consequence, intrinsic positive end-expiratory pressure (PEEP) is present in grossly obese subjects especially in the supine position. The investigators tried to investigate the effect of low respiratory rate and high tidal volume on the intrinsic PEEP and gas exchange for obese subjects undergoing general anesthesia.
Studies evaluating intraperitoneal local anesthetic instillation for pain relief after laparoscopic procedures have provided conflicting results. This randomized, double-blind study was designed to assess the effects of a novel intraperitoneal local anesthetic administration technique using nebulization on pain relief after laparoscopic cholecystectomy.
Intraperitoneal nebulization of local anesthetic is a novel approach to pain management after laparoscopy. Preoperative compared with postoperative administration of analgesia remains controversial. This randomized, double blind, placebo-controlled trial compared the analgesic efficacy of preoperative with postoperative peritoneal ropivacaine nebulization in patients undergoing elective laparoscopic cholecystectomy.
The investigators postulated that the use of hyperventilation after induction of anesthesia before CO2 insufflation for laparoscopic surgery in Trendelenburg position would maintain normocapnia and reduce the hemodynamic percussion response of CO2 insufflation.
The purpose of this study is to assess if intraperitoneal nebulization of Ropivacaine 50 mg, 100 mg or 150 mg may prevent the use of morphine during the first day after laparoscopic cholecystectomy.
Standard cystic duct cholangiography (CDC) during laparoscopic cholecystectomy can be difficult, time consuming and bile duct injury may be caused by attempts to cannulate the cystic duct. Operative cholangiography performed by direct puncture of the gall bladder fundus or Cholecystocholangiography (CCC) is a valid and easier alternative.
The purpose of this study is to determine whether Transversus abdominis plane block as part of a multimodal postoperative regimen is superior to control in analgesic efficacy after laparoscopic cholecystectomy.
Although laparoscopic cholecystectomy is associated with less pain than contemporary open procedures; it is definitely not pain free and the magnitude of postoperative shoulder and abdominal pain in the early postoperative period is still quite significant. This postoperative pain is a major concern not only for the patients, but also healthcare workers; and it often contributes to overnight hospital stay after this minimally invasive surgical procedure. Intraperitoneal instillation of local anesthetics at the time of surgery to control pain after laparoscopic cholecystectomy has been extensively studied in numerous randomized trials and found to be extremely useful. Lignocaine and Bupivacaine are two commonly used local anesthetic agents. In view of contradictory results from previous studies, it is not yet clear which of these two agents is superior to the other for pain control in this setting. To answer this question, we have designed a prospective randomized controlled trial and the specific aim of the study is to compare the analgesic efficacy of intraperitoneal lignocaine with intraperitoneal Bupivacaine in the postoperative setting after laparoscopic cholecystectomy. If we can improve pain control after this minimally invasive procedure, it might result in decreased postoperative requirement of narcotic analgesia and its associated side-effects. It may also result in early recovery and the same day discharge of the patients with significant cost-containment for the patient and healthcare systems in future.
double blind study of kidney function of two groups of adult patients submitted to laparoscopic cholecystectomy and analgesia from tramadol associated to dipyrone or ketorolac
