Filter by:The aim of this research project is to compare electrocautery to scalpel for laparotomy skin incisions, with the following objectives: 1. To investigate whether electrocautery produces a cosmetically inferior surgical scar. 2. To compare the rates of wound infection with each technique. 3. To determine if electrocautery results in less postoperative pain. Our null hypothesis is that electrocautery is equivalent to scalpel for creating skin incisions; with respect to wound cosmesis, wound infection rate, and post-operative pain.
Transanal Endoscopic Microsurgery (TEM) is a minimally invasive technique used to remove rectal tumours. After the tumour has been removed from the rectum, the surgeon has a choice to close the defect or leave the defect open and naturally close. Currently, both options are accepted as standard care. Leaving the defect open to close naturally has some possible advantages, including shortened operation time and similar rates of postoperative complications. However, there is some concern that not surgically closing the defect may lead to more postoperative pain and delay in recovery. The study will be a double blind randomized controlled trial and determine whether patients who have rectal wall defect sutured closed have less post-operative pain compared to patients whose defect is left open.
This study is a single-center, randomized, placebo-controlled, double-blind clinical trial. The purpose of this study is to evaluate the impact of pre-operative transverses abdominis plane (TAP) blocks on post-operative analgesia in patients undergoing robotic surgery for gynecologic cancers.
The investigators hypothesize that patient controlled analgesia (PCA) provides superior pain relief and patient satisfaction when compared to scheduled intravenous analgesia following vaginal reconstructive surgery.
Cerebral palsy is common. It affects approximately 3 per 1000 children. Hip displacement due to muscle tightness (spasticity) occurs in up to half of the more severely affected children, and many of these children require major (bony) hip surgery. After bony hip surgery the management of pain is very difficult, as spasticity tends to increase and causes painful spasms which are difficult to control. Botulinum Toxin injections are known to reduce spasticity and therefore should also reduce pain. These injections take at least a week to work, but the effects can last for months. Botulinum Toxin is already an established treatment for chronic hip pain prior to surgery. The investigators aim to find out whether Botulinum Toxin injections can reduce post-operative pain. The identification of the level of pain can be challenging because most of these children are unable to communicate verbally. The investigators are therefore using a validated pain scoring tool that was designed especially for such children. This study will be the first to describe fully the pain experience of children with cerebral palsy undergoing this type of major surgery. The investigators will compare Botulinum Toxin injections with placebo (non-active) injections. There is a high emotional and financial burden on the families of these children. Families describe high levels of emotional distress around the time of surgery, particularly when their child is in pain. Difficulty with pain control post operatively may delay discharge from hospital and parental return to work. It causes disrupted sleep for the child and family and may delay the child's return to school. The results of this study will be shared with professionals and families at international conferences and in scientific and popular (patient-based) publications. This study cannot be undertaken in adults with cerebral palsy as they only rarely undergo this sort of surgery.
Objective :To compare the analgesic effect of intrathecal clonidine and fentanyl as an additive to bupivacaine in patients undergoing cesarean section . Methods:Following Ethics Committee approval and informed patients consent, Ninety patients 18-45 yr old ASA physical status I or II, scheduled for cesarean section under spinal anesthesia, were studied in a prospective, double-blinded, randomized way. The patients were randomly allocated to one of three groups of 30 each. The clonidine group (groupC) received bupivacaine 10mg combined with 75microgram clonidine preservative free ,the fentanyl group (group F) received bupivacaine 10mg combined with25microgram fentanyl and the placebo group (group P) received bupivacaine 10mg combined with 0.5ml distilled water intrathecally . Time to first requirement of analgesic supplement, Sensory block onset time, maximum sensory level , onset of motor block, duration of blockade, hemodynamics variables, the incidence of hypotension, ephedrine requirements, bradycardia ,hypoxemia [Saturation of peripheral oxygen (SpO2)<90], postoperative analgesic requirements and Adverse events, such as sedation, dizziness , Pruritus and postoperative nausea and vomiting were recorded. Patients were instructed preoperatively in the use of the verbal rating scale (VRS) from 0 to 10 (0no pain, 10maximum imaginable pain) for pain assessment. If the VRS exceeded four and the patient requested a supplement analgesic, diclofenac Na supp 100 mg was to be given for post-operative pain relief as needed . For breakthrough pain(VRS >4) if time of administration of diclofenac Na less than 8h,Pethidine 25 mg IV was given.
Objective :To compare the analgesic effect of intrathecal midazolam and ketamine as an additive to bupivacaine in patients undergoing cesarean section . Methods:Following Ethics Committee approval and informed patients consent, Ninety patients 18-45 yr old ASA physical status I or II, scheduled for cesarean section under spinal anesthesia, were studied in a prospective, double-blinded, randomized way. The patients were randomly allocated to one of three groups of 30 each. The ketamine group (groupK) received bupivacaine 10mg combined with 0.1 mg/kg ketamine preservative free ,the midazolam group (group M) received bupivacaine 10mg combined with0.02 mg/ kg midazolam and the placebo group (group P) received bupivacaine 10mg combined with 0.5ml distilled water intrathecally . Time to first requirement of analgesic supplement, Sensory block onset time, maximum sensory level , onset of motor block, duration of blockade, hemodynamics variables, the incidence of hypotension, ephedrine requirements, bradycardia ,hypoxemia [Saturation of peripheral oxygen (SpO2)<90], postoperative analgesic requirements and Adverse events, such as sedation, dizziness , Pruritus and postoperative nausea and vomiting were recorded.

This study will compare the effects of oral pregabalin with placebo on postoperative pain and morphine usage after mastectomy. Pregabalin is an anticonvulsant agent approved by the United States Food and Drug Administration (FDA) for the treatment of neuropathic pain associated with post-herpetic neuralgia and diabetic neuropathy. Women 18-70 years of age, undergoing unilateral modified mastectomy or lumpectomy with axillary node dissection will be recruited to participate in the study. Patients unable to cooperative, those that have known allergy to pregabalin or morphine and a history of drug or alcohol abuse, chronic pain, history of daily intake of analgesics or steroids, or impaired kidney function will all be excluded from the study. A pregnancy test will also be performed to exclude pregnant women from the study. Oral pregabalin 300 mg (or placebo) will be administered to patients 1-2 hours before surgery followed by 150 mg 12 hours later. Thereafter, 150 mg of oral pregabalin (or placebo) will be administered twice daily until day 14. Whether a patient receives pregabalin or placebo will be decided based on a process similar to tossing a coin. Patients will receive a standard general anesthetic for their operation and will receive intravenous patient-controlled analgesia (PCA) morphine for pain in the immediate postoperative period. Oral opioids will be administered after discontinuation of the PCA. Subjects will be visited after the operation while in the hospital and intermittently for three months at the outpatient clinic after discharge from the hospital. Subjects will be asked to return remaining study drug/empty container when they are at the hospital for their 2 week follow up visit. Potential adverse effects of pregabalin include dizziness, somnolence, peripheral edema, weight gain, headache, dry mouth, blurry vision, and ataxia. The incidence of these side effects occurring ranges variously between 1 and 25%. Investigators will closely monitor all patients for the occurrence of these side effects.
This study was originally undertaken to evaluate the analgesic efficacy of an intravenously administered dose of ketorolac compared with intravenous morphine in the relief of acute, postoperative pain in children admitted to the Intensive Care Unit. Using the urine and plasma samples originally collected from patients in the morphine treatment group and which were never analyzed, this proposal seeks to study the pharmacokinetics and metabolism of intravenous morphine in critically-ill children along with its concentration-related efficacy using prior measures of pain.
Patients who have abdominal surgery will experience pain from the incision. The lumbar TAP block is a procedure used to reach the nerve endings in the abdominal wall so that there is a reduction in pain after surgery. Using ultrasound guidance, a solution of ropivacaine will be injected after surgery. The aim of this study is to determine the effect of changes in the volume of the injection.
