Background: Succinylcholine is the most anesthetic drug used to muscle relaxation in emergency endotracheal intubation. Unfortunately it can have serious side effects. The perpose of our study was to comparison of Atracurium + Alfentanyl with succycholine. Materials and Methods: In this clinical trial study, one hundred patient randomly designated two group succinylcholine (control group) & At...

The histamine releasing potential of equivalent bolus doses of atracurium 0.6 mg kg-1 or vecuronium 0.12 mg kg-1 was evaluated in 20 children anaesthetized with halothane. Blood samples were obtained before, and at 2 and 5 min after the administration of the neuromuscular blocker. The twitch response to 0.15 Hz was also evaluated. None of the 10 patients receiving vecuronium had a significant i...

laryngeal mask is a supraglothic instrument for ventilation of patients who are under anesthesia. insertion of laryngeal mask requires maintaining sufficient depth of anesthesia to avoid airway reflex (gagging, coughing and spasms). the present study investigated two techniques of anesthesia with propofol-atracurium and thiopental-atracurium to facilitate insertion of the laryngeal mask, term o...

The aim of this study was to investigate the effects of sevoflurane on skeletal muscle contractility. In the first part, twenty-two American Society of Anesthesiology (ASA I-II) female adult patients undergoing elective hysterectomy surgery inhaled sevoflurane 1.0, 1.5 and 2.0 minimum alveolar concentrations (MAC) in succession. Neuromuscular function was assessed at each dose. In the second pa...

We have studied the effect of doxapram on the rates of spontaneous and neostigmine-induced recovery from neuromuscular block with atracurium and vecuronium, by measurement of the time to recovery of T1 (first twitch in the train-of-four) from 25 to 75% of control (recovery index, RI). After each neuromuscular blocking drug, RI was measured without administering either doxapram or neostigmine (c...

Forty patients received tubocurarine in a dose greater than ED90. When neuromuscular function had recovered to amplitude of the first contraction of the train-of-four equals 10% of control, a small increment of atracurium or vecuronium was administered, repeating the same increment at each subsequent recovery to 10%. The intensity and duration of the neuromuscular block following the first incr...

In a controlled, randomized study, we evaluated duration of neuromuscular block in 80 patients undergoing routine abdominal surgery. Forty patients were aged 18-50 yr (control group) and 40 patients were more than 65 yr (elderly group). All patients had normal plasma creatinine concentrations. After induction of anaesthesia, patients were allocated randomly to receive either atracurium 0.5 mg k...

BACKGROUND With its introduction for widespread clinical use, there has been an increase in reports of bronchospasm related to the administration of rapacuronium. As it is commonly used for rapid sequence intubation, it has been suggested that these effects may be related to an inadequate depth of anesthesia. The current study examines the airway effects of rapacuronium in tracheally intubated,...
