Filter by:The purpose of this study is to compare a closed-loop intravenous anesthetic using Bispectral Index as a feedback loop and a controller based on reinforcement learning to titrate dose and intravenous anesthetic that is manually controlled or a standard volatile anesthetic agent titrated by the anesthesiologist to determine improvement in the following parameters as compared to controls: time to discharge from the Post Anesthesia Care Unit, post-operative nausea and vomiting, pain scores and sedation scores.
Increase of intracerebral pressure (ICP) during laparoscopic surgery has known to be associated with positional changes. Optic nerve sheath diameter (ONSD) has correlation with ICP and ultrasonographic measurement of optic nerve sheath diameter (ONSD) is known to be a noninvasive and rapidly applicable technique for evaluating ICP. The aim of this study is to investigate the change of ONSD according to the positional change during laparoscopic surgery.
Percutaneous cholecystostomy (PC) is an effective treatment for cholecystitis in surgical high risk patients. However, there has been no definite agreement of the additional cholecystectomy in these patients. The investigators surveyed the clinical outcomes of the PC in surgical high risk patients. And the investigators tried to prove the PC can be appropriate and ultimate treatment for acute cholecystitis patients with critical illness through this study.
Opioids may attenuate postoperative hyperalgesia and postoperative nausea and vomiting. Our hypothesis is: opioid-free total intravenous anesthesia with propofol, dexmedetomidine and lidocaine infusions for laparoscopic cholecystectomy may achieve comparable hemodynamic stability during laparoscopy, with lower postoperative analgesic consumption and incidence of postoperative nausea and vomiting.
In patients with pancreatic duct cannulation initially by chance, double guide wire technique and trans pancreatic sphincterotomy facilitate biliary cannulation and show the similar success rates. The incidence of post-procedure pancreatitis was similar in the two groups, but post-procedure hyperamylasemia was significantly higher in the DGT group.
Laparoscopic surgery has become the golden standard for the removal of the gallbladder. Recently, developments have been made so that operations can be performed through a natural orifice instead of the abdominal wall, thus minimizing the trauma of a procedure. This study compares the transvaginal/transumbilical cholecystectomy with the laparoscopic operation using 2-3mm instruments in female patients. It also examines the benefits and disadvantages related to postoperative pain, cosmetic aspects, and potential physiological alterations to the transvaginal approach that affect sexual intercourse.
Laparoscopic cholecystectomy (removal of the gall bladder via 'keyhole surgery') is a common procedure. This can be performed as an emergency operation when a patient has a complication of gall stones such as acute inflammation or pancreatitis. There are several trials which demonstrate that placing local anaesthetic inside the abdomen at the site of gall bladder surgery during a planned elective operation decreases post operative pain. This is the first trial to investigate the efficacy of this local anaesthetic during emergency cholecystectomy.
The purpose of this study is to evaluate if cholecystectomy first (studied group) versus sequential common bile duct imaging/cholecystectomy (control group) result in a decrease of hospital stay, morbidity/mortality and costs in the management of patients with a suspicion of gallstone migration.
The objective of this study is to determine whether the finger tip images captured by the EPIC ClearView device, when analyzed via the ClearView software, produce a Response Scale that characterizes trends consistent with known diagnoses identified by medical doctors. Specifically, the investigators hypothesize that the organ system involving any of a series of known active diagnoses will be identified in the EPIC ClearView Response Scale report with the intention of providing potential triage capabilities.
This study is planning to develop the audiovisual videos and determine whether educational videos are superior to routine discussion for informing patients in the emergency department (ED) about risks, benefits, and alternatives to receiving percutaneous cholecystostomy. Eligible patients will be approached when patients will be scheduled and waiting for receiving percutaneous cholecystostomy in the emergency department.
