Randomized Controlled Trial
Gastrointestinal motility following thoracic surgery: the effect of thoracic epidural analgesia. A randomised controlled trial.
Impairment of gastrointestinal (GI) motility is an undesirable but inevitable consequence of surgery. This prospective randomised controlled study tested the hypothesis that postoperative thoracic epidural analgesia (TEA) with ropivacaine or a combination of ropivacaine and morphine accelerates postoperative GI function and shortens the duration of postoperative ileus following major thoracic surgery compared to intravenous (IV) morphine. ⋯ Objective tests demonstrated the delayed motility of the whole GI system postoperatively following thoracic surgery. They also demonstrated that continuous epidural analgesia with or without morphine improved GI motility in comparison to intravenous morphine. These differences were more pronounced on the third postoperative day.

Comparative Study
A comparison of the use of propofol alone and propofol with midazolam for pediatric magnetic resonance imaging sedation - a retrospective cohort study.
Pediatric MRI sedation performed by a variety of specialists such as sedationists and anesthesiologists commonly uses propofol, which has similar effects to an ideal sedative agent for maintaining deep sedation. However, when propofol is used, adverse airway events are relatively more common than when using other sedative agents. The concomitant administration of midazolam and propofol can reduce the dose of propofol needed for adequate sedation and might also reduce the frequency of airway obstruction without affecting the patient's recovery profile. ⋯ The administration of a small dose of midazolam during pediatric MRI sedation using propofol can reduce the frequency of airway complications without prolonging the clinically significant recovery profile.

Randomized Controlled Trial
Staggering the dose of sugammadex lowers risks for severe emergence cough: a randomized control trial.
Cough on emergence has been reported as a common adverse reaction with sugammadex reversal. We investigated if staggering the dose of sugammadex will reduce emergence cough in a single-center, randomized, double-blinded study. ⋯ Staggering the dose of sugammadex for reversal will effectively decrease common emergence and early postoperative complications.

Head fixation can induce hemodynamic instability. Remifentanil is commonly used with propofol for total intravenous anesthesia (TIVA) during neurosurgery. This study investigated the 90% effective concentration (EC90) of remifentanil for blunting of cardiovascular responses to head fixation during neurosurgery via bispectral index (BIS) monitoring. ⋯ Adjustment of the Ce of remifentanil to approximately 6.5 ng/mL before head fixation could prevent noxious cardiovascular responses in 90% of neurosurgical ASA I-II patients aged 20 to 65 years old during propofol target-controlled infusion titrated to maintain BIS between 40 and 50.

To describe a case of an accidental epidural potassium infusion leading to an acute transient spinal paralysis and cardiac symptoms and review the literature on that topic. ⋯ A symptom complex with elevated sympathetic nervous system activity up to a stress cardiomyopathy is possible following epidural potassium infusion. Additionally, generalized pain and muscle spasticity evolve and a progressive acute spinal cord injury syndrome can occur within minutes, accompanied by respiratory depression. Treatment consists of early intensive care and the symptomatic therapy of the associated symptoms, leading in most of the reported cases to a good clinical outcome.
