Filter by:Total Knee Replacement (TKR) performed under general anesthesia is a common successful orthopedic procedure. Nonetheless, in elder patients with diabetes mellitus (DM) this procedure can present unique challenges to orthopedic surgeon and anesthesiologist alike. Many diabetic patients have clinical or subclinical neuropathy. Although there is no evidence that the neuropathy is exacerbated by neural blockade, recent studies have suggested that the peripheral nerves in diabetic patients may be more susceptible to trauma and local anaesthetic toxicity. Therefore, The investigators observe peripheral nerve blocks with ropivacaine on diabetic patients or non-diabetic patients undergoing TKR by assessing the management of intraoperation and the Postoperative Recovery and complications.
Postoperative recovery is always worrisome to the elder patients undergoing Total Hip Replacement (THR). Peripheral Nerve Blocks (PNBs), lumbar plexus block combined with sciatic nerve blocks, may be alterative anaesthesia style to the fragile patients. But pervious papers suggested PNBs were commonly administered in conjunction with general anesthesia (GA), or the blocks were performed primarily for postoperative analgesia. Hardly any research has reported in use of Peripheral Nerve Blocks (PNBs) as primary anesthesia style for Total Hip Replacement (THR). The investigators compare peripheral nerve blocks to general anesthesia on elderly eld patients undergoing Total Hip Replacement (THR) by assessing the Postoperative Recovery and Delirium
Study of time usage of anesthesia team inside the main operating room compares between 2 groups of - Performing regional anesthesia inside the operating room - Performing regional anesthesia in the block room Study purpose: How much will the investigators save time in the main operating room if we perform the regional anesthesia in the block room?
The current study is designed to investigate the difference of plasma orexin A levels between elderly and young patients at emergence from sevoflurane-fentanyl anesthesia who will undergo elective lumbar surgery.
In modern cardiac surgery and cardiology Transcatheter Aortic Valve Implantation (TAVI) is an emerging procedure for high-risk patients that are assumed to be otherwise inoperable. The investigators want to evaluate the specific intraoperative anesthesiologic characteristics cardiac anesthesiologists have to face during these procedures.
the target of this study is to assess the minimum alveolar concentration of sevoflurane to maintain theBispectral Index below 50.The minimum alveolar concentration (MAC) for maintaining Bispectral Index below 50 (MACBIS50) of sevoflurane has been reported previously in adult with Body Mass Index ( BMI) < 40 to be 0.97 and in enfant to be 2.83%, However, there is no study assessed theBispectral Index below 50 (MACBIS50 ) in morbidly obese patient (BMI > 40). The first aim of our study is to assess the MACBIS50 of sevoflurane in morbidly obese patients BMI 40 - 70 using the Continuous Reassessment Method (CRM) in 80 % of patients.
Neuraxial anesthesia affords a less interventional way to desensitization of the lower body for surgical procedures. After introduction of neuraxial anesthesia, vasodilatation of body part below the anesthetic level is theoretically appeared as the sympathetic nerve efferent is blocked. The vasodilatation effect is related to hypotension, hypothermia, shivering and the response of volume redistribution. It is believed that vasodilatation leads to better regional tissue perfusion and better regional tissue oxygenation. Previous reports of laser doppler flowmetry and thermography showed their effectiveness on monitoring blocked level but they were not easily available in the operation room. Recently Near-infrared spectroscopy(NIRS) demonstrates real-time tissue oxygen saturation(rSO2) which is applied generally in non-invasive brain oximeter. We use NIRS in spinal anesthesia to monitor the tissue oxygenation change over the upper and lower limbs during the induction of neuraxial anesthesia.
- Hypothesis: - X-tip intraosseous is an effective supplementary injection in mandibular hot teeth as well as Periodontal Ligament (PDL) injection - Purposes: - Comparing the anesthetic efficacy of X-tip intraosseous and PDL injection in mandibular hot teeth which had not been anesthetized after 3.6 ml Infra Alveolar Nerve Block - Methods and Materials: - forty patients with mandibular hot molar or second premolar which had not been anesthetized after 3.6 ml inferior alveolar nerve block injection will be selected for this study
We previously evidenced in both animal models and patients that a short duration ambulatory anesthesia impacts the circadian rest-activity biological rhythm, at least during the first 3 days. The light is the main, natural synchronisateur, of the biological cerebral clock, and is used as therapeutics in chronic disturbances of the circadian rest activity rhythm and of the sleep (Alzheimer disease for example). We would like to test for a simple and safe strategy to prevent such a long-lasting effect of anesthesia on biological clock:the increase of the light intensity at a still physiological level during the initial phase of recovery from anesthesia by using a particular artificial light of color spectrum similar to natural sun daylight.
The Study is designed to collect information about adverse events that occur in children undergoing anesthesia in participating hospitals. Demographic information will be collected on all anesthetics. An analysis of each adverse event will be performed and entered into the database. From this information we will devise strategies to prevent these adverse events.
