Filter by:The drawbacks of chemical CO2 absorbers include the production of compounds harmful to patients that also lead into increased cost and environmental impact, as well as the daily disposal of compound special waste. Sustainable management of general anesthesia is a growing concern. Continually diluting anesthetic circuits, and the disposal of chemical granulate are serious environmental problems.
Peritoneal dialysis (PD) catheter placement surgery for patients with end-stage renal disease (ESRD) can be performed under peripheral nerve block. This study assessed the ability of ultrasound guided left lateral transversus abdominis plane (TAP) block combined with rectus sheath (RS) block in PD catheter placement surgery. Also, surgeries are common surgeries performed in elderly patients throughout the world. Although there is an increasing trend towards laparoscopic surgeries, open procedures continue to remain common therapeutic modalities especially in the developing countries. Pain is reported more commonly in patients undergoing open procedures than laparoscopic procedures. Postoperative pain and tissue injury associated with surgery initiated a systemic stress response which has neuroendocrine, immunological, and haematological responses. Opioids are an important modality of postoperative pain management. They blunt the neuroendocrine stress response to pain. However, they are associated with several adverse effects like respiratory depression, nausea, vomiting , pruritus, constipation, urinary retension, bradycardia and hypotension. Transversus abdominis plane block（TAPB）is a relative novel procedure in which local anesthetic agents are injected into the anatomic plane between the internal oblique and the transversus abdominis muscle. It allows a significantly prolonged duration of analgesia during the early postoperative stage in abdominal surgery. This regional anesthesia technique provides analgesia to the skin, muscles of the anterior abdominal wall and parietal peritoneum in order to decrease the incision-related pain. Thus, it reduces postoperative opiate requirements and opioids-related side effects (nausea, vomiting, delayed resumption of intestinal transit, drowsiness, respiratory depression, urine retention). Nalbuphine, being mu antagonist an kappa agonist, has a ceiling effect in its respiratory depression. Many studies have reported that incidence of adverse effects like pruritus and PONV is lower with nalbuphine in comparison with morphine. The purpose of this study is to compare the analgesic efficacy and side effect profile of sulfentanyl with nalbuphine in elderly patients undergoing open gastrointestinal surgeries.
Monitoring data during anesthesia of surgical patient in the operation room will be collected and stored into the registry automatically. Patients' information and preoperative assessment from medical records will be included. Furthermore, intraoperative events will integrated and entered in the registry. The purpose of the registry is to establish an automatic and accessible database of surgical patients for further retrospective studies.
The purpose is to calculate the time for an optimal recovery (T4/T1 > 0.9) from the moment when 2 responses to double burst stimulation are visually identical and this for 95% of patients.
This will be a multicentre, randomised, controlled and prospective clinical trial. All participants provided their written informed consent to participate in a randomized trial that examined the effects of low-level MAP (60-70 mmHg) vs. high-level MAP (90-100 mmHg) in elderly patients (65 or more years of age) during noncardiothoracic surgery under general anesthesia. The investigators hypothesise high-level blood presure of the intervention for reducing the incidence of post-operative complications.
Narcotrend index is a widely used quantitative parameter for evaluating anesthesia and sedation levels.Dexmedetomidine is a novel sedative,providing sedation while patients remain cooperative and can be easily aroused. This study was designed to explore the correlation of Narcotrend index and OAA/S scale in monitoring sedation level with different single- doses of dexmedetomidine intravenously.
The aim of this retrospective study is to evaluate the preferred anaesthesia techniques in our clinic for emergency orthopedic surgery at a 1 year period.
Dexmedetomidine, a selective alpha2-adrenergic agonist is known to reduce propofol and opioid requirements due to its sedative and analgesic properties. However, until now, there has been studies based on indirect measures such as hemodynamics. Entropy shows to quantify the level of consciousness by EEG and Surgical pleth index(SPI) allows to predict the effect of pain stimuli and analgesic therapy by the index of the nociception-anti-nociception balance. The investigators analyzed quantitatively the requirements of propofol and remifentanil under continuous infusion of dexmedetomidine when using entropy and SPI.
Propofol is a well-known induction agent which can provide sound and quick hypnosis with anti-emetic effects. However, dose dependent hypotension or bradycardia have reported while using this agent. Propofol in combination with remifentanil or midazolam can result in synergistic or additive effect in elderly patients. There are not many studies which provide minimum dose of propofol to induce hypnosis in combination with these agents and advantage of the combination. The elderly patients (over 65 years old) who are scheduled to undergo general anesthesia are enrolled in this study. 120 patients will be randomly allocated to 3 groups(P, PR, PMR). Sample size have been decided due to the previous studies which have mentioned 40 participants as a adequate sample size for this biased coin design - up and down study. After receiving informed consent, patients will be participated in this study. No premedication will be given to the patients before induction. The patients in group P will receive general anesthesia only with propofol and group PR and PMR will receive 0.125 mcg/kg/min remifentanil infusion for 5 min prior to propofol administration. The patients in group PMR will receive 0.015 mg/kg bolus dose of midazolam 1 min after the start of the remifentanil infusion. Initial propofol dose will be 0.5 mg/kg in each group and the dose will be changed by the result of prior study participant. 'Success' of this study will be defined as loss of both verbal response and eyelash reflex in 3 min after propofol administration. When 'success', the next patient will receive the same dose(in 18/19 probability) or 0.125 mg/kg lower dose(in 1/19 probability) of propofol. When 'failure', the next patient will receive 0.125 mg/kg higher dose of propofol at induction period.
Autism Spectrum Disorder (ASD) is the fastest growing neurodevelopmental disorder in the world. Approximately 1% of the population worldwide is affected by this disorder. Children with ASD exhibit some very stereo-typical behaviors. Their daily functionality depends on very rigid and predictable schedules and routines. Any changes in their schedules can often trigger negative emotional outbursts. The need to come to the hospital for procedures can be one such trigger. The purpose of this study is to examine the post anesthesia behavior outcomes of children with ASD.
