Previous studies comparing Glidescope and classic direct laryngoscopy did not show an attenuation of CV responses to endotracheal intubation. In the present study, we hypothesize that indirect videolaryngoscopy can attenuate cardiovascular responses to endotracheal intubation. In a randomized cross-over study, eighty adults (ASA PS II-III) were included. Both direct and ...

Obstructive sleep apnea (OSA) is characterized by episodes of repeated airway obstruction resulting in cessation (apnea) or reduction (hypopnea) in airflow during sleep. These events lead to intermittent hypoxia and hypercapnia, sleep fragmentation, and changes in intrathoracic pressure, and are associated with a marked surge in sympathetic activity and an ...

Patients undergone mechanical ventilation need rapid and reliable evaluation of their respiratory status. Monitoring of End-tidal carbon dioxide (ETCO2) as a surrogate, noninvasive measurement of arterial carbon dioxide (PaCO2) is one of the methods used for this purpose in intubated patients. The aim of the present trial was to study ...

Salt sensitivity of blood pressure has been studied in humans with a 48-hour inpatient protocol of salt loading and depletion or with longer outpatient protocols using high- and low-salt diets. Results have been reproducible, but both methods are laborious and costly. A 6-hour protocol of intravenous salt loading and furosemide ...

Achievement of goal blood pressure values, particularly in high-risk categories of patients, still remains an unmet goal of the therapeutic approach to hypertension. The same conclusion can be drawn for patient adherence to antihypertensive drugs, which is a variable of major relevance for obtaining optimal blood pressure control in treated ...

The Food and Drug Administration (FDA) is classifying the hemorrhoid prevention pressure wedge into class II (special controls). The special controls will apply to the device in order to provide a reasonable assurance of safety and effectiveness of the device. A hemorrhoid prevention pressure wedge provides support to the perianal ...

Introduction: Previous studies have demonstrated that hypertensive patients need concomitant therapy with one or more drugs from different classes of antihypertensive agents to achieve their blood pressure control targets. We performed the first multinational observational study of valsartan/hydrochlorothiazide (HCTZ) single pill combination in Asia to determine the efficacy, safety, and ...

BACKGROUND: The scapula locator method has associated intra-observer and inter-observer errors caused by the dependency on the observer to locate the scapular landmarks. The potential effect of the pressures applied by the observer on the measured scapular kinematics when this method is used has also been overlooked so far. The ...

Twelve healthy cattle (weighing 188-835kg) were placed in stocks and sedated with xylazine. Caudal epidural puncture was performed using an acoustic device that indicated a decrease in resistance with a change in pitch. Lidocaine was injected to verify correct needle placement by assessing needle prick stimuli applied on the left ...

If the patient's breathing circuit becomes disconnected during a high-airway-pressure event, Draeger Medical's Evita series and Savina ventilators may continue to display an "Airway Pressure High" alarm message, rather than appropriately displaying the "Airway Pressure Low" message. This may distract staff from the true hazard, potentially inhibiting or delaying care ...

The Surgical Pleth Index (SPI) is proposed as a means to assess the balance between noxious stimulation and the anti-nociceptive effects of anaesthesia. In this study, we compared SPI, mean arterial pressure (MAP), and heart rate (HR) as a means of assessing this balance. We studied a standard stimulus [head-holder ...

Anaesthesia requires maintenance of a patent airway. Nasotracheal intubation of a red kangaroo (Macropus rufus) was performed when the inability to open the animal’s mouth prevented orotracheal intubation. Nasotracheal intubation was easy to perform, secured the airway and permitted delivery of supplemental oxygen, isoflurane and intermittent positive pressure ventilation.

Epidural anesthesia is commonly utilized in veterinary medicine to allow diagnostic, obstetrical, and surgical intervention, in the perineal region of domestic animal. The following study was carried out to directly compare the time of onset and duration of anesthesia produced by a tramadol and lidocaine-tramadol combination with that produced by ...

The aim was to investigate if intraoperative registrations of blood pressure and heart rate could be used to estimate surgical trauma. In a prospective clinical trial, registrations in eight dogs neutered by laparoscopic ovariectomy (LOE) were compared with eight dogs subjected to open ovariohysterectomy (OHE). For comparisons phases were used: ...

Background: Laryngoscopy and endotracheal intubation are known to cause increase in both arterial blood pressure and heart rate. Several strategies have been evolved to blunt the haemodynamic response to tracheal intubation but each method has its own advantages and disadvantages. Esmolol, a cardio selective Beta -1 blocking drug, can alleviate ...

Several studies have demonstrated that ephedrine shortens the onset time of muscle relaxants, and it does so probably by increasing the cardiac output. However, elevation of the systemic blood pressure through α adrenergic stimulation via ephedrine may affect the onset of muscle relaxants during the induction of anesthesia. We investigated ...

Beta-1-receptor blockade reduces heart rate, cardiac output, and arterial pressure while increasing peripheral vascular resistance. It is possible that beta blockers not only inhibit the core-to-peripheral re-distribution of body heat and cutaneous heat loss due to vasodilation after anesthesia induction but also reduce the convective transfer of heat from the ...

BACKGROUND: Neuraxial anaesthesia improves tissue perfusion and tissue oxygen tension. Vasodilation induced by this technique may result in hypotension requiring the administration of vasoactive drugs. The use of peripheral vasoconstrictors might counteract the improved tissue perfusion and its potentially beneficial effects. We therefore investigated the effect of i.v. norepinephrine and ...

Hypotension after spinal anaesthesia is a common and important complication at caesarean delivery. Skin conductance monitoring has been shown to predict post-spinal hypotension in elderly patients and may be a rapid, non-invasive means of predicting risk in the obstetric population. Women having elective caesarean delivery were included in this observational ...

Takayasu's arteritis is a rare form of nonspecific obliterative panarteritis of unknown aetiology. Anaesthesia for patients with Takayasu's arteritis is complicated by severe uncontrolled hypertension leading to end-organ dysfunction, stenosis of major blood vessels affecting regional circulation, and difficulties in the monitoring of arterial blood pressure. The anaesthetic approach for ...

The aim of this study was to determine the effect of thiamylal and propofol on heart rate-corrected QT (QTc) interval during anaesthetic induction. We studied 50 patients undergoing lumbar spine surgery. Patients were administered 3 microgxkg(-1) fentanyl and were randomly allocated to receive 5 mgxkg(-1) thiamylal or 1.5 mgxkg(-1) propofol ...

Landiolol is a new ultra-short-acting beta 1-selective adrenoreceptor antagonist, which is metabolized rapidly by plasma cholinesterase (PCHE). Metoclopramide has been shown to inhibit PCHE in vitro. Therefore, metoclopramide might prolong beta blocking effects of landiolol and spoil its ultimate-short-acting property. Just before induction of anesthesia, gynecological patients were randomly assigned ...

BACKGROUND AND OBJECTIVE: The blind intubation device (BID) was introduced for awake nasotracheal intubation recently. The aim of this study was to compare the cardiovascular responses and associated airway complications of fibreoptic bronchoscope (FOB) with those of BID. The intubation attempts and intubation time were also compared. METHODS: Forty-one ASA ...

Rapid intravenous injection of oxytocin is associated with marked hypotension secondary to decreased venous return. Reductions in dose and rate of bolus administration have reduced the incidence of cardiovascular side effects, but no study has yet investigated cardiovascular stability when oxytocin is infused for several hours after delivery. This study ...
