Filter by:TITLE: EFFECT OF SHORT-TERM PRANAYAMA ON ANAESTHESIA MANAGEMENT IN PATIENTS UNDERGOING CARDIAC SURGERY Primary aim: To evaluate the effect of pre-operative short term pranayama yoga on stress-induced hemodynamic (HR, MAP) changes in patients scheduled for cardiac surgery. Secondary aims: 1. To compare the effect of YOGA on preoperative anxiety. 2. To compare the effect of Yoga on SPO2. 3. To compare effect of Yoga on total consumption of propofol administered using Closed Loop Anaesthesia Delivery system(CLADS) 4. To compare effect of Yoga on total consumption of fentanyl, and vecuronium 5. To compare effect of Yoga on post-operative anxiety (after extubation in CTVS ward) 6. To compare effect of Yoga on postoperative outcome in terms of duration of mechanical ventilation, duration of ICU stay, incidence of complications and post-op mortality
Anaesthesia has three major components, analgesia, muscle relaxation and hypnosis. For a long time, opioids have been covering the analgesia function. (1) When using opioids, an analgesic effect is obtained per-operatively, however, not without side-effects. Post-operative complications such as: respiratory depression, post-operative nausea and vomiting, pruritus, acute opioid tolerance and hyperalgesia, difficulty voiding and ileus, are well known. Opioid usage is an important risk factor of postoperative desaturation. Postoperative desaturation can lead to severe hypoxemia and even tissue hypoxia, followed by obvious cardiologic and neurological complications. Thus, in patients at risk, such as the obese patient, experts suggest reducing opioid usage. Non-opiate protocols implemented on the obese patient have been published. Non-opiate protocols have been established using a combination of ketamine, lidocaine and an alpha-2 agonist. The main purpose of this pilot study is to evaluate whether patients undergoing an opioid free anaesthesia regime experience less desaturation episodes during the first 24 h post-bariatric surgery than patients having received an opioid anaesthesia regime.
The purpose of this study is to determine which technique for catheter placement in continuous femoral nerve block (FNB) is most successful - guidance with (1) ultrasound or (2) nerve stimulation and ultrasound. Sensory and motor assessment scores will be obtained post-FNB. Patient controlled analgesia and opiate consumption is also recorded along with pain scores for the first 48 hour post-FNB.
There is no consensus regarding which alternative is the best anesthesia for breast surgery, general anesthesia and morphine for postoperative analgesia or a combination of regional anesthesia and general anesthesia that possibly attenuates or abolishes the need for morphine. The current study aims to determine which of the two strategies that is best in relation to postoperative pain, nausea and risk of recurrence of the disease.
Modern anesthesia has made a lot of progress, however, postoperative pain remains one of the major problems associated with patient discomfort, prolonged hospital stay and increased health care costs. Remifentanil is an ultra-short-acting phenylpiperidine opioid analgesic with high lipid solubility and a rapid onset of effect. Recently, opioid use has also been associated with postoperative opioid-induced hyperalgesia or acute opioid tolerance. An immediate discontinuation of remifentanil has been associated to increased postoperative pain levels. We would like to investigate whether a gradual post-operative withdrawal of remifentanil is indeed associated with less immediate pain compared to after an abrupt withdrawal in surgical patients undergoing minor surgery.
During routine general anesthesia (not standardized, left to the discretion of the attending anesthesiologist), pupillary pain index was measured one minute before skin incision. Then, variations in heart rate, blood pressure and bispectral index during the three minutes following skin incision were recorded, as well as the occurrence of movements.
To explore and compare antihyperalgesic effects of Dexmedetomidine,Nalmefene,and a combination of both received before anesthesia induction. To evaluate and examine the incidence of adverse effects with the purpose of selecting the optimum dose.
Perioperative fluid management is crucial for patients' outcome. Muller et al developed a "Mini-fluid challenge method " to predict fluid responsiveness and the efficacy. The investigators design the study to investigate the effectiveness of mini-fluid challenge test in prone position surgery.
The use of videolarygoscopy (VL) as first choice for tracheal intubation versus direct laryngoscopy (DL) is a matter of debate. These two methods were compared in several studies. Videolaryngoscopes may reduce the number of failed intubations, particularly among patients presenting with a difficult airway. They improve the glottic view and may reduce airway trauma. DM is accepted as a risk factor for difficult intubation. The aim of this study is to compare VL to DL in adult patients requiring tracheal intubation for anesthesia, in terms of intubation success, glottic view quality, intubation failure, intubation time, conversion to another laringoscopy method and adverse outcomes related to tracheal intubation.
The purpose of this randomized, observer-blinded, investigative trial is to determine if the use of electrical stimulation, compared to the traditional loss of resistance technique alone, improves the success rate of epidural catheter placement at an academic teaching institution.
