antiemetic/hypoxia

The sleep apnea-hypopnea syndrome (SAHS) involves periods of intermittent hypoxia, experimentally reproduced by exposing animal models to oscillatory PO₂ patterns. In both situations, chronic intermittent hypoxia (CIH) exposure produces carotid body (CB) hyperactivation generating an

BACKGROUND Nausea and vomiting are frequent adverse effects of patient-controlled epidural analgesia (PCEA) with opioids. OBJECTIVE This study was designed to assess the antiemetic effect of midazolam added to fentanyl-ropivacaine PCEA. METHODS In a prospective, randomized, double-blind, controlled

Nausea and vomiting during the infusion of cryopreserved peripheral blood stem cells (PBSC) are common. The aim of this study was to explore the effect of lollipop with strawberry aroma on the infusion-related nausea and vomiting of cryopreserved autologous PBSCs. We compared 2 groups of adult

Substance abuse is prevalent in adolescent street children, and death is reported as secondary to aspiration, accidental trauma, asphyxia, cardiac arrhythmia, anoxia, vagal inhibition and respiratory depression. In this study, we examined electrocardiographic and echocardiographic findings from 53

Palliative and end of life care forms an important part of the role of any doctor in training, and an awareness of a structured approach to managing common symptoms and end of life care is essential. Common symptoms include pain, nausea and vomiting, constipation, and breathlessness. Anticipatory

Forty-nine patients undergoing elective total hip replacement received either morphine or meptazinol for postoperative analgesia from a patient-controlled analgesia apparatus. Ventilatory rate and volume and arterial oxyhaemoglobin saturation were recorded continuously for the first 24 h following

Recent studies have shown that the antiemetic neuroleptic drug, prochlorperazine, is a potent stimulant of the ventilatory response to hypoxia. To investigate whether or not this effect persisted in the presence of central depression of ventilatory drive, the effects on ventilatory control of

BACKGROUND Diphenhydramine is used as an antipruritic and antiemetic in patients receiving opioids. Whether it might exacerbate opioid-induced ventilatory depression has not been determined. METHODS The ventilatory response to carbon dioxide during hyperoxia and the ventilatory response to hypoxia

This study compared the prophylactic antiemetic efficacy and the adverse effects of 0.5 mg droperidol, 5.0 mg metoclopramide, and placebo for outpatients undergoing gynecological laparoscopy under conscious sedation. One hundred and fifty outpatients were randomly allocated, in a randomized

BACKGROUND Management of cesarean section with spinal anesthesia is often accompanied with intraoperative nausea and pain. In a randomized controlled study, we explored the effect of intrathecal fentanyl on the characteristics of subarachnoid block in patients undergoing cesarean

BACKGROUND This project studied pain control and the development of adverse events before, during, and after the administration of hydromorphone hydrochloride for various interventional radiology (IR) procedures. METHODS We performed a retrospective analysis of 100 patients (men = 58; women = 42)

OBJECTIVE Olanzapine is a second-generation antipsychotic increasingly used in emergency medicine for many indications. Literature on its use in children is sparse. Our objectives were to describe the use, safety, and efficacy of olanzapine in pediatric emergency patients. METHODS A structured chart

BACKGROUND Intrathecal opioids routinely are administered to surgical patients to provide prolonged postoperative analgesia. This study evaluated the dose-response effects of intrathecal fentanyl in an elderly patient population undergoing lower extremity revascularization

Tumour cell hypoxia is a recognized cause of resistance to radiotherapy. Using clinically relevant dose-fractionation schedules in a mouse tumour model, the addition of carbogen and nicotinamide to overcome chronic and acute hypoxia results in a marked increase in radioresponsiveness with a lower

In ophthalmic surgery, children are anesthetized for various reasons. The airway needs special attention as children have higher oxygen requirements and brief periods of apnea can result in hypoxemia and subsequent bradycardia or even cardiac arrest. Most interventions can be managed with the aid of
