Randomized Controlled TrialPretreatment with remifentanil is associated with less succinylcholine-induced fasciculation.
Succinylcholine is a popular muscle relaxant and one of its most common side effects is muscle fasciculation. The purpose of this study was to evaluate the efficacy of remifentanil in preventing succinylcholine-induced fasciculation in patients undergoing general anesthesia. ⋯ Our findings indicate that remifentanil can reduce the duration and the intensity of succinylcholine induced fasciculation. However, it induces greater bradycardia.

ReviewUpdate on anesthesia considerations for electroconvulsive therapy.
Depression is diagnosed in 14 million Americans every year, and pharmacotherapy is the standard treatment. However, in approximately 50% of patients, pharmacology intervention does not resolve depression. Electroconvulsive therapy (ECT) has been a mainstay as a treatment option for treatment-resistant major depression since its inception in the 1930s. ⋯ The clinical anesthesiologist must be aware of these changes as well as have an understanding of perioperative pharmacological interventions. ECT is a proven therapy for select psychiatric patients, and appropriate anesthesia is a critical part of successful ECT. Careful review of the patient's medical history may reveal pertinent anesthetic considerations.

Major obstetric hemorrhage is an extremely challenging obstetric emergency associated with significant morbidity and mortality. Pharmacological treatment of uterine atony has not altered much in recent years apart from the increasing use ofmisoprostol, although controversy surrounds its advantages over other uterotonics. ⋯ Interventional radiology may reduce blood loss in these cases. Uterine compression sutures, intrauterine tamponade balloons and cell salvage have been introduced in the last decade.

Randomized Controlled Trial Comparative StudyLabor analgesia in preeclampsia: remifentanil patient controlled intravenous analgesia versus epidural analgesia.
Epidural analgesia is considered to be the preferred method of labor analgesia in preeclamptic patients. Systemic opioids are another good effective, easy to administer alternative but may cause maternal and fetal respiratory depression. Remifentanil's rapid onset and offset of effects, should make it an ideal drug for the intermittent painful contraction during labor. Method. 30 preeclamptic patients were randomly assigned to one of two equal groups; Epidural Group: received epidural analgesia according to a standardized protocol using bupivacaine plus fentanyl. REMIFENTANIL GROUP: PCA was set up to deliver remlfentanil 0.5 microg/kg as a loading bolus infused over 20 seconds, lockout time of 5 minutes, PCA bolus of 0.25 microg/kg, continuous background infusion of 0.05 microg/kg/min, and maximum dose is 3 mg in 4 hours. Women were advised to start the PCA bolus when they feel the signs of a coming uterine contraction. ⋯ PCA intravenous remifentanil is an effective option for pain relief with minimal maternal and neonatal side effects in labor for preeclamptic patients with contraindications to epidural analgesia or requesting opioid analgesia.

Case ReportsGranular cell myoblastoma of tongue: a rare cause of unanticipated difficult intubation.
Intubation with direct laryngoscopy may be impossible in 0.05%-0.35% patients due to an undetected supraglottic mass despite an apparently normal pre-operative airway assessment. We report a case of granular cell myoblastoma of the tongue, as a cause of an unanticipated impossible intubation. ⋯ A 55-year-old ASA III male weighing 75 Kg was taken up for emergency exploratory laparotomy with perforation peritonitis. On preoperative airway examination there was no indication of difficult intubation. After induction of anesthesia (rapid sequence with rocuronium) we performed direct laryngoscopy. There was a mass arising from the base of the tongue because of which no recognizable epiglottis or glottic structure could be identified. Despite repeat laryngoscopy, optimal external manipulation and direct laryngoscopy performed by an ENT surgeon, the airway could not be secured. As no fibreoptic laryngoscope was available, a surgical tracheostomy had to be performed.
