Observations have been made of pupil size, as affected by intravenously administered atropine and neostigmine, and by extubation, during reversal of curarization. Pulse rate and blood pressure changes were also recorded. Some degree of mydriasis was observed in 70 per cent of patients after atropine, in 86 per cent after neostigmine, and in 55 per cent at extubation. Pulse rate increased in 88 ...

ROSECRANS, J. A. AND E. F. DOMINO. Comparative effects of physostigmine and neostigmine on acquisition and performance o f a conditioned avoidance behavior in the rat. PHARMAC. BIOCHEM. BEHAV. 2(1) 67-72 , 1974. The actions of physostigmine (0.10 and 0.15 mg/kg) and neostigmine (0.12 mg/kg) given s.c. on acquisition and performance of conditioned pole jumping were studied in rats receiving eith...

We studied 100 healthy women undergoing outpatient gynaecological laparoscopy in a randomized, double-blind and placebo-controlled study to evaluate the effect of neostigmine on postoperative nausea and vomiting (PONV). After induction of anaesthesia with propofol, anaesthesia was maintained with sevoflurane and 66% nitrous oxide in oxygen. Mivacurium was used for neuromuscular block. At the en...

BACKGROUND Epidural administration of neostigmine appears to be safe in the obstetric population. Recently, few studies have concluded 10 μg sufentanil to be an effective adjuvant with epidural neostigmine in providing labor analgesia. However, no study has evaluated the analgesic effect of epidural butorphanol with neostigmine for the same. MATERIALS AND METHODS The parturients were randomly...

BACKGROUND The primary outcome of sugammadex reversal for rocuronium-induced neuromuscular block (NMB) is a train-of-four ratio (TOFR) of 0.9, not first twitch (T1) height. We investigated whether the recovery of TOFR or T1 differs based on the reversal of NMB with neostigmine or sugammadex. METHODS The acceleromyographic responses from 0.6 mg/kg of rocuronium were monitored supramaximally in...

BACKGROUND This study evaluated the efficacy of an epidural single dose of neostigmine combined with sufentanil to provide selective and balanced analgesia at the beginning of labor. METHODS After informed consent, 125 healthy parturients were randomly allocated to receive, after a test dose, a single injection of either epidural sufentanil 20 micrograms (minimal analgesic dose) or 10 microgr...

BACKGROUND Animal models of visceral pain have gained much attention as an important tool to elucidate the possible mechanisms underlying functional gastrointestinal (GI) disorders. Here we report the development of a new, minimally invasive behavioral model of abdominal pain induced by ip administration of neostigmine in mice. METHODS Spontaneous behavioral responses evoked by ip injection o...

BACKGROUND Sugammadex is a modified γ-cyclodextrin with a novel mechanism of action for reversing the steroidal neuromuscular blocking agent rocuronium. Bispectral index (BIS) is an EEG-derived measure which can be sensitive to frontal electromyographic (EMG) artifacts. We compared BIS values before and after sugammadex or neostigmine neuromuscular block (NMB) reversal in patients with or witho...

The occurrence of acute postoperative respiratory failure in three patients with renal failure is presented. The most likely cause was the return of muscle paralysis after the apparent antagonism of tubocurarine by neostigmine (recurarization). In addition to reducing the dose of tubocurarine, the authors recommend that pyridostigmine be used as an antagonist instead of neostigmine because the ...

the present work with consideratlon to the autoradiographic pictures, suggests that cholinergic receptors are located at the gate of a channel originating from synaptic cleft coming to lie within the muscle fibre. ache molecules stand at the gate of this channel,controlling the entrance of different cholinergic agents. it was report- ••• ed previously that dtc molecules s t.abd ;:.2e the ache r...
