The effect of acute ethanol administration into the cerebral ventricles on the unanesthetized cat upon emesis produced by norepinephrine and clonidine injected similarly as well as upon emesis evoked by copper sulfate given orally was compared and investigated. Ethanol inhibited the norepinephrine-
The effect of acute ethanol administration into the cerebral ventricles of the unanesthetized cat upon emesis produced by norepinephrine and nicotine injected similarly was investigated. Ethanol inhibited the norepinephrine- and nicotine-induced emesis. The inhibitory effect of ethanol occurred
OBJECTIVE
The authors studied whether metoclopramide decreases the incidence of emesis after spinal anesthesia supplemented with subarachnoid morphine.
METHODS
Patients underwent total hip arthroplasty under spinal anesthesia using tetracaine with norepinephrine and morphine 0.2 mg. Forty-eight
Opioids are effective analgesics used clinically for both acute and chronic pain management. However, repeated opioid treatment can induce serious side effects such as nausea, vomiting, drowsiness, respiratory depression, euphoria, dependence, hyperalgesia, and tolerance. The mechanism of noxious
Objective: To investigate the efficacy and safety of prophylactic infusion of norepinephrine (NE) versus normal saline in patients undergoing cesarean section.
Methods:
The prevalence of takotsubo syndrome (TTS) in patients with subarachnoid hemorrhage (SAH) is much higher than in the general population. Clinical and experimental observations confirm secondary to brain damage catecholamine-mediated cardiac injury resulting in reversible left ventricular (LV)
Phenylephrine is the current "gold standard' vasopressor used to treat maternal hypotension in women undergoing cesarean delivery with spinal anesthesia. Since 2015, various studies have explored the use of norepinephrine to manage maternal hypotension. We conducted this Probenecid administered in divided oral doses totaling 100 mg/kg increased levels of norepinephrine (NE) in plasma and cerebrospinal fluid (CSF). This technique is commonly used to measure the rate of accumulation of acidic metabolites of certain brain neurotransmitter biogenic amines in CSF after
BACKGROUND
The pathophysiology behind post-operative nausea and vomiting (PONV) is still not fully understood, especially with respect to gender. According to PONV risk scores, female gender is the strongest predictor for PONV. The risk for PONV after general anaesthesia for breast cancer surgery is
The localized effect of noradrenergic agonists administered directly in the anterior hypothalamic preoptic area (AH/POA) in inducing emesis in the cat was investigated. Of the noradrenergic agonists tested, which included norepinephrine, clonidine, phenylephrine and methoxamine, only clonidine in
Cisplatin is an effective antineoplastic agent that causes severe vomiting due to unknown mechanism. The ferret, an animal model useful in the determination of emetic activity, was used to clarify the emesis-related biochemical and histopathological changes that were induced by cisplatin. Cisplatin
The purpose of the present study was to develop a controllable experimental model in the dog that would consistently and predictably produce a malignant hypertensive crisis, and to determine the sequential changes in renal function, salt and water balance, and hormones that are involved in the
The emetic action of dopamine, norepinephrine, epinephrine, nicotine, dimethylphenyl-piperazinium (DMPP), and 4-m-chlorophenylcarbamoyloxy-2-butynyltrimethylammonium (McN-A-343) injected intracerebroventricularly (i.c.v.) to the unanesthetized cat was investigated and compared. ED50 values (mg) were
Acute tryptophan depletion (ATD) is a method of lowering brain serotonin (5-HT). Administration of large neutral amino acids (LNAA) limits the transport of endogenous tryptophan (TRP) across the blood brain barrier by competition with other LNAAs and subsequently decreases serotonergic
OBJECTIVE
To analyze the neurochemical profile during the recurrent attacks of nausea and vomiting in patients with Riley-day syndrome.
BACKGROUND
One of the most disabling features of patients with Riley-day syndrome are recurrent attacks of severe nausea/retching/vomiting accompanied by
