Filter by:This is a prospective cohort study to explore the differences of resting-state functional magnetic resonance imaging (fMRI) between elderly gastrointestinal neoplasms patients with postoperative delirium (POD) who either develop or do not develop long-term postoperative neurocognitive disorders (pNCD).
This prospective observational study aims to compare days alive and out of hospital at 30 days (DAOH-30) in patients with poor or good functional capacity undergoing gastrointestinal surgeries. The investigators are testing the hypothesis that patients with good functional capacity will have longer days alive and out of hospital than those with poor.
The goal of this observational study is to compare Incidence of postoperative delirium in Sarcopenic and non-sarcopenic elderly patients undergoing gastrointestinal surgery. The main question it aims to answer are: • Effect of preoperative sarcopenia on postoperative delirium in elderly patients undergoing gastrointestinal surgery Participants will be evaluated preoperatively for sarcopenia and assessed for postoperative delirium, pain, etc.
Objective To evaluate the effect of patient-controlled intravenous analgesia combined with different opioid receptors for gastrointestinal surgery. Methods A total of 4342 patients who underwent gastrointestinal postoperative analgesia in the first affiliated Hospital of Air Force military Medical University from May 2018 to March 2022 were collected retrospectively. The patient-controlled intravenous analgesia regimen in this study was composed of different opioid receptor drugs：sufentanil combined with nalbuphine group (SN group) and Hydromorphone combined with nalbuphine group (HN group) and single opioid receptor group: sufentanil group (S group). SN group ,HN group and S group were treated with sufentanil 100 μ g + nalbuphine 40 mg, hydromorphone 10 mg+ nalbuphine 40 mg, sufentanil 200 μ g, diluted to 100 ml, background dose 1 ml/h, PCA dose 0.5 ml, locking time 10 min. The demographic data of the three groups were collected, the number of patients with insufficient static and dynamic analgesia (VAS ≥ 4) at 24 and 48 hours after operation, the adverse reactions at 24 and 48 hours after operation, the first exhaust time and the first ambulation time were collected, evaluate the analgesic effect of combination of different opioid receptor drugs and single opioid receptor drugs in PCIA after gastrointestinal surgery.
Surgical pain refers to pain that occurs immediately after surgery, including physical pain and visceral pain. Thus, it severely challenges the proper use of analgesics for patients undergoing laparoscope gastrointestinal surgery to clinicians. Nalbuphine is a mixed agonist-antagonist opioid. The investigators hypothesized that the clinical effect of nalbuphine in combination with dexmedetomidine might be different from that of sufentanil in combination with dexmedetomidine. So, the investigators performed a nalbuphine and dexmedetomidine dose finding study, for the patient controlled anaesthesia (PCA) after the laparoscopic gastrointestinal surgery, to establish their 95% effective dose (ED95). The investigators then compared the clinical effect and adverse events of the newly established dosing regimen of nalbuphine combined with dexmedetomidine, to the equivalent dosing of sufentanil combined with dexmedetomidine, in the same patient population.
For non-diabetic patients undergoing gastrointestinal surgery, preoperative oral carbohydrate improves postoperative recovery. The purpose of this pilot study is to investigate the impact of preoperative oral carbohydrate (outfast®) on the recovery in diabetic patients after gastrointestinal surgery.
It is a prospective, randomized, placebo-controlled study to investigate the effect of TEA with different block level on propofol concentration during general anesthesia induction.
Objectives: Since 2007, natural orifice surgery evolved from theory and animal research to clinical applications, but is still limited in the literature to small casuistic reports. A preliminary prospective evaluation of postoperative results of the early casuistic of Natural orifice Surgery for many indications may show advantages and disadvantages of the methods. The IMTN Multicenter Trial for Clinical NOTES was and early results are described.
The study was designed to test the hypothesis that immunonutrition and enteral nutrition would reduce the incidence of infectious complications in a population of malnourished patients following elective upper GI surgery
