Filter by:Anterior cruciate ligament reconstruction is a routine surgical procedure. Traditional femoral/sciatic block combinations effectively reduce postoperative pain, but results in considerable motor blockade. The investigators aimed to evaluate postoperative pain relief and the degree of motor block with block combinations of femoral nerve (FEM) and obturator [posterior branch] nerve (ONP), versus saphenous nerve (SAPH) and ONP, versus placebo blocks with isotonic saline. All patients received standard patient controlled analgesia with morphine.Randomized, placebo-controlled and double-blinded clinical trial. Following IRB approval, 81 patients were planned to be randomized to one of three USG block combinations: Active FEM+ONP, active SAPH+ONP or no active blocks (sham blocks) Ropivacaine 0.75% was used for all active blocks following induction of general anaesthesia [propofol-remifentanil, laryngeal mask airway]. Primary outcome measure: Localized PACU pain scores (AUC) 0-6 hours postoperatively at rest. Secondary outcome measures: Opioid consumption, opioid related side effects, PACU time, motor abilities of daily living scores [modified Barthel/100 index], perceived ill health [Short form-8] scores and degree of motor blockade [Jensen- Børglum motor test].
In this study, we wish to investigate the effect of ultrasound (US) -guided block of the saphenous nerve (SN) and the posterior branch of the obturator nerve (ONP) on postoperative pain and the use of opioids (morphine-like pain medicine) in the first 24 hours following ambulatory knee arthroscopy. We wish to investigate the analgesic effect of these two blocks compared to placebo (injection of local anesthetic with known pain blocking properties compared with injection of a saline solution), when used as a supplement to conventional oral analgesics. We hypothesize that patients receiving the active treatment may experience less pain during the first 24 hours after their operation than patients receiving the placebo treatment, and possibly require less opioid analgesics, experience less opioid related side effects and have a higher function level in this period than patients receiving the placebo treatment.
The purpose of this study is to determine if an intravenous lidocaine infusion (compared to placebo) intraoperatively will decrease time to return of bowel function postoperatively, decrease postoperative pain, diminish postoperative opioid requirement, minimize inflammatory markers and shorten time to discharge after colorectal surgery.
The investigators are investigating two ways of treating pain after hip surgery. One way is though a thin tube (called a catheter), and it is placed into the back so that pain-numbing drugs can reach the nerves near the backbone. This is called an "epidural" catheter. Another way is to place the catheter close to the hip, where the surgery is done, so that the pain-numbing drugs can reach some of the nerves more locally. This is called a "fascia iliaca compartment" catheter. The investigators do not know which way is best to treat pain, or has fewer side effects, or allows a patient to leave hospital faster. Usually, patients would receive only one type of catheter for pain relief. To do this comparison, the investigators would place both catheter types, so that patients help us tell which one works better.
The hypothesis of this study is that controlled release oxycodone can be safe and well tolerated for the control of postoperative pain in surgery for head and neck cancer. The primary objective is to study the safety and the incidence and severity of adverse effects, and the secondary objective is to evaluate the analgesic efficacy and identify the frequency of use of rescue medication and the prescribing physician's opinion about the quality of postoperative analgesia with oxycodone controlled release in oncologic surgery of the head and neck.
The purpose of this study is to investigate the effects of music on patients after surgery in the Post Anesthesia Care Unit (PACU). For many patients, surgery creates significant emotional stress and anxiety which can include discomfort or pain. Music therapy has proven to be a useful adjuvant in various inpatient and outpatient settings by providing a relaxing effect that decreases heart rate, blood pressure, and hormonal measures of stress. It has been shown that classical music can cause physiological and psychological differences in patient outcomes, but few studies have looked specifically at effects of jazz music. Some have argued that jazz may be too involved to provide the same relaxed state as classical music, but this may be due in part to the type of jazz played for the patient. It is our hypothesis that slow jazz music by artists including Miles Davis, Ella Fitzgerald, Diana Krall, Dave Brubeck, etc. will reduce measures of stress and anxiety in patients in the PACU following surgery for hysterectomy (laparoscopic or robotic) to a greater extent than the control group. Jazz music or "no music" will be played through headphones to participants in the study post-surgically while they are in the PACU and measures of stress, anxiety, and pain will be monitored.
The aim of this study is to compare the efficacy of methadone versus morphine in dealing with postoperative pain, in laparoscopic cholecystectomy under total intravenous anesthesia (TIVA); Efficacy is defined in terms of the difference of milligrams in morphine used as rescue analgesia postoperatively. Our hypothesis is that methadone is more effective than morphine for postoperative pain treatment.
There is a large variability of postoperative pain intensity and of the drug doses necessary to alleviate this pain. The investigators hypothesis is that a measurement of nociception at the end of surgery, using either the RIII reflex threshold, measures of heart rate variability or the pupil dilatation reflex measured by pupillometry, in relation to the doses of opioids used intraoperatively will yield a prediction of postoperative pain.
Exparel is a new local analgesic (numbing medication) that is intended to be longer acting than currently available local analgesics. The purpose of this study is to determine whether use of Exparel to numb the nerves along the breastbone after open heart surgery, will decrease pain and pain medication use after surgery.
Pectus excavatum (PE) is a common chest wall deformity where the sternum is displaced posteriorly. In severe cases, surgery is performed to correct the defect (1). In recent years, minimally invasive surgery with the placement of stainless steel support bars has been increasingly performed in patients over the age of 17 years (1-9). Because of the decreased malleability and tremendous pressure required to hold the chest wall in the corrected position, post-operative pain control has been a significant problem in this patient population (2,6,9-12). Thoracic epidurals are commonly employed however mean hospitalizations of up to 7 days have been required before adequate pain control on oral analgesics is obtained (3-5, 13) and patients are suitable for discharge. It is hypothesized that using the ONQ system (I-Flow Corporation, Lake Forest CA) with bilateral intercostal catheter infusion would provide adequate post operative pain control with a significantly shorter hospital length-of-stay than thoracic epidural. Total use of narcotics for 1 week following surgery would also be less with the ONQ system versus epidural.
