Filter by:In this study the investigator will address the efficacy of using low dose bupivacaine spinal anesthesia (SA) in combination with epidural volume extension (EVE) for patients undergoing short obstetric procedures.
This study will address the utility of ultrasound in the placement of an epidural catheter in severely obese parturients. Identification of midline can often be difficult using the standard method of palpation in obese patients. The Investigator will determine if the use of ultrasound decreases the amount of time and number of attempts required to place the epidural.
Sixty neonates and infants will be enrolled and randomised into two groups of n=30 each . For their surgical procedures, one group general (GA) anaesthesia the second group will receive a combined general and epidural anaesthesia (CGEA). Anaesthetic technique: Patients in the GA group will be induced with intravenous propofol (2-4 mg.kg-1) and fentanyl (2-4 µg.kg-1) and will receive rocuronium bromide (0.5 mg.kg-1) to facilitate endotracheal intubation. Anaesthesia will be maintained with sevoflurane (2-3%) in an air/oxygen mixture as well as intravenous fentanyl as required. In the (CGEA) 0.5 ml.kg-1 of 0.25% bupivacaine will be injected into the epidural catheter, followed by a continuous infusion of 0.1% bupivacaine at a rate of 0.2 mg.kg-1.hr-1 for up to 48 hours postoperatively. Assessment of anaesthetic efficacy will be measured Intraoperative care vital signs. And will continuously be monitored with a Datex AS/3 (Engestrom®, Helsinki, Finland) monitor. The use of antibiotic prophylaxis will be determined by the degree of bowel contamination during surgery, with the commonest regimen consisting of penicillin, gentamicin and metronidazole will be administered. Antibiotics will be continued for 36-48 hours postoperatively to prevent infection arising from the disturbed bowel flora. Postoperative care, following surgery, will be conducted. The feeding volume will be increased in steps as long as the volume of regurgitated fluid will be less than 20% of the administered breast milk or formula volume. Full feeding will define as oral tolerance of at least 80% of daily maintenance volume. In cases of abdominal distension or vomiting, feeding will withheld until symptom resolution. The nasogastric tube will be removed on bowel function restoration The CRIES score will be use to assess the severity and duration of postoperative pain during the patients' NICU stay. If the CRIES score is ≥4, fentanyl will be continuously intravenously infused in both study group. Fentanyl will be also administered to CGEA patients who experienced pain despite a continuous epidural infusion at 1-5 µg.kg-1.h-1. The amount of fentanyl required for adequate postoperative pain relief will be recorded in both groups.
Surgical resection is one of the most important treatments for resectable cancer; on the other hand, cancer recurrence and/or metastasis are the major reasons of treatment failure. The development of recurrence/metastasis after cancer surgery mostly depends on the balance between the immunity of human body and the capability of implantation, proliferation and neovascularization of the residual cancer. Preclinical and retrospective clinical studies suggest that anaesthetic management may affect the long-term outcomes after cancer surgery. The investigators hypothesize that use of epidural anesthesia-analgesia may improve long-term survival in elderly patients after major surgery for cancer.
To explore the effect of heating precondition of epidural catheter on the incidence of injury to blood vessel during epidural catheter placement.
The study will assess the benefit of using spinal ultrasound before epidural catheter insertion compared to the conventional palpation technique in women undergoing cesarean section.
Postoperative delirium is a common complication in elderly patients after surgery. Its occurrence is associated with worse outcomes. The pathophysiology of delirium remains poorly understood. However, an universal phenomenon is that delirium frequently occurs in elderly patients after major complicated surgery, but is rarely seen after minor ambulatory surgery (such as cataract surgery). This indicates that stress response produced by surgery might have an important role in the pathogenesis of delirium. It has been reported that, when compared with general anesthesia and postoperative intravenous analgesia, neuraxial anesthesia and analgesia reduced the occurrence of postoperative complications and mortality in high risk patients. Combined epidural-general anesthesia is frequently used in clinical practice. This anesthetic method provides advantages of both epidural and general anesthesia, i.e. it blocks the afferent pathway of nociceptive stimulus by neuraxial blockade during and after surgery, and allows patients to endure long-duration surgery without any awareness. The investigators hypothesize that combined epidural-general anesthesia and postoperative epidural analgesia can decrease the incidence of delirium in elderly patients after major surgery when compared with general anesthesia alone and postoperative intravenous analgesia.
In this trial, the investigators intend to examine whether the concentration of local anesthetics during epidural analgesia could be modulating factor for change of hemodynamics in patients undergoing major upper abdominal surgery.
Comparison of epidural anesthesia and general anesthesia for laparoscopic cholecystectomy, patients in the surgery and the effectiveness of anesthesia after surgery, the incidence of side effects or complications, and postoperative recovery of the body of the differences
Specific Aim: The purpose of this study is to determine if labor epidural placement using real-time (concurrent) ultrasound guided placement is superior to the conventional "standard" epidural technique without the use of ultrasound at Magee-Womens Hospital. Hypothesis: Ultrasound guided labor epidural placement in real-time will decrease the traditional epidural failure rate from 5% to 1%.
