Ultrasound-guided spinal anesthesia in an obese patient.

We describe the case of 62-year-old man with a body mass index of 53, hypertension, diabetes mellitus and obstructive sleep apnea that was proposed for transurethral resection of prostate under spinal anesthesia. The surface landmark-guided approach was difficult and was abandoned after many unsuccessful attempts. Spinal anesthesia was achieved in one attempt with ultrasound guidance using the midline approach at the identified level.

Lidocaine reduces endotracheal tube associated side effects when instilled over the glottis but not when used to inflate the cuff: A double blind, placebo-controlled, randomized trial.

Background: Tracheal intubation results in an alteration of the laryngeal mucosa which can lead to undesirable effects at emergence from anaesthesia. Local anesthetics, when administered topically, may represent an interesting alternative to reduce these side effects.

Aim: In this trial, we aimed to evaluate the effect of lidocaine in preventing tracheal intubation related side effects at emergence from anaesthesia, when instilled onto the glottis before intubation or used to inflate the endotracheal tube cuff.

Myocardial ischemic conditioning: Physiological aspects and clinical applications in cardiac surgery.

Ischemia-reperfusion is a major determinant of myocardial impairment in patients undergoing cardiac surgery. The main goal of research in cardioprotection is to develop effective techniques to avoid ischemia-reperfusion lesions. Myocardial ischemic conditioning is a powerful endogenous cardioprotective phenomenon.

Ultrasound does not shorten the duration of procedure but provides a faster sensory and motor block onset in comparison to nerve stimulator in infraclavicular brachial plexus block.

Background: Infraclaviculr Brachial plexus (ICBP) block is useful for upper extremity surgery. The aim of this study was to compare the ultrasound (US) technique with the nerve stimulation (NS) technique in their success rates and times to perform ICBP block.

Methods: 60 patients undergoing surgery of the upper limb were randomly allocated into two groups (n = 30 per group).

A Case of Horner's Syndrome following Ultrasound-Guided Infraclavicular Brachial Plexus Block.

Horner's syndrome results from paralysis of the ipsilateral sympathetic cervical chain (stellate ganglion) caused by surgery, drugs (mainly high concentrations of local anesthetics), local compression (hematoma or tumor), or inadequate perioperative positioning of the patient. It occurs in 100% of the patients with an interscalene block of the brachial plexus and can also occur in patients with other types of supraclavicular blocks.In this case report, we presented a case of Horner's syndrome after performing an ultrasound-guided infraclavicular brachial plexus block with 15 mL of bupivacaine 0.
