Penile intracavernosal injection of succinylcholine for laryngospasm management during hypospadias repair

UroPrecision, EarlyView.
Abstract Background Laryngospasm is a serious anesthetic complication that can lead to acute airway obstruction and hypoxemia. Standard management involves deepening anesthesia and administering succinylcholine intravenously (IV) or intramuscularly (IM). However, if IV access is lost or IM drug delivery is too slow, alternative routes are required.

Prediction of preload dependency using phenylephrine-induced peripheral perfusion index during general anaesthesia: a prospective observational study

BMC Anesthesiology
Background Tracking preload dependency non-invasively to maintain adequate tissue perfusion in the perioperative period can be challenging.The effect of phenylephrine on stroke volume is dependent upon preload.

Hemodynamic Effects of Prolonged Apneic Oxygenation in Laryngologic Surgery: A Randomized Controlled Pilot Trial

World Journal of Otorhinolaryngology - Head and Neck Surgery, EarlyView.
ABSTRACT Background Limited data exist on cardiocirculatory responses associated with extended periods of apnea during administration of high‐flow nasal oxygen for laryngologic surgery (apneic oxygenation with HFNO, AO‐HFNO). The possibility of hemodynamic compromise in the settings of acute hypercapnia, respiratory acidosis, hyperoxia, and IV ...

Impact of Prophylactic Weight-Based Phenylephrine Infusion on Shivering During Cesarean Delivery– A Prospective Randomized Controlled Trial

Journal of Obstetric Anaesthesia and Critical Care
Background: Shivering during cesarean delivery under spinal anesthesia is an undesirable complication. Intravenous phenylephrine infusion, at varying doses, decreases the intensity of redistribution hypothermia with no consensus on ideal dosing regimen ...

β-Receptor agonist activity of phenylephrine in the human forearm

, 2001
Phenylephrine is generally regarded as a “pure” α1-agonist. However, after treatment of the forearm with the α-adrenergic-blocking drug phentolamine, brachial artery infusion of phenylephrine can cause transient forearm vasodilation.

Updated EAACI Statement on Drug Hypersensitivity Skin Testing: Methodology and Non‐Irritative Concentrations

Allergy, EarlyView.
ABSTRACT These updated EAACI guidelines aim to standardize skin testing methodologies for both immediate and non‐immediate drug hypersensitivity reactions. For immediate reactions, the optimal testing window is 4–6 weeks post‐reaction; whereas beyond 6 months, false‐negative results increase.

Effect of topical phenylephrine on the equine pupil. [PDF]

, 1987
The mydriatic effect of 10% phenylephrine was evaluated in 9 horses. Base-line pupillary size in mesopic conditions and during light stimulation was ascertained before application of pharmacologic agents. In study 1, 10% phenylephrine was applied to each

Comparative Outcomes of Early versus Delayed Penile Prosthesis Insertion in Patients With Ischaemic Priapism—Long‐Term Outcome Experience From a Single High‐volume Centre

Andrology, EarlyView.
ABSTRACT Background and Objectives Ischaemic priapism (IP) is a urological emergency that can lead to erectile dysfunction (ED) if not treated promptly. This study aims to evaluate and compare clinical outcomes between early and delayed penile prosthesis insertion in patients with IP.

An assay for phenylephrine applicable to stability studies

, 1974
An assay specific for phenylephrine, in the presence of decomposition products, is described. The procedure depends on the separation of the active constituent by cationic exchange resin and the subsequent determination of the ultraviolet absorbance at ...
