Do the Concentration and Volume of Local Anesthetics Affect the Onset and Success of Infraclavicular Anesthesia?

Background: Although local anesthesia is a suitable method for upper limb surgeries, there is debate regarding the effects of appropriate dosing.

Objectives: In the current study, we investigated the effects of the concentration and volume of a local anesthetic on the beginning and quality of anesthesia during upper limb orthopedic surgeries.

Patients And Methods: This double-blinded, randomized, clinical trial was conducted on 60 patients aged between 18 and 85 years candidated for upper limb orthopedic operations.

Propofol and alfentanil in treatment of a patient with episodic cluster headache.

Introduction: Cluster headache is a severe hemifacial pain with concomitant symptoms such as lacrimation, conjunctival congestion, and nasal discharge. Peripheral (to be a spectrum of trigeminal autonomic cephalgia) and central (hypothalamus) disorders have been suggested to be involved. Several modalities have been recommended to prevent or alleviate this devastating headache.

Use of laryngeal mask airway in children with upper respiratory tract infection, compared with face mask: randomized, single blind, clinical trial.

Objective: The incidence of postoperative cough (primary outcome) and adverse respiratory events (secondary outcome) in children who received anesthesia by laryngeal mask airway (LMA) with children who received anesthesia by face mask (FM) was compared in a blind randomized trial with uncomplicated upper respiratory track infection (URI) undergoing general anesthesia. Previous studies of pediatric patients with URI receiving anesthesia by endotracheal tube have reported a greater number of anesthetic complications; however reports concerning adverse effects in pediatric patients with URI receiving anesthesia by LMA or FM are scanty.

Method: For the present trial, 150 children with uncomplicated URI and requiring general anesthesia for ophthalmic procedures were enrolled.
