BACKGROUND AND OBJECTIVES: Cardiac tamponade is potentially fatal medical condition, which rarely occurs as a complication of lung lobectomy. We present the first case of cardiac tamponade to develop in a Post-Anesthesia Care Unit following a lung lobectomy. CASE REPORT: A 54-year-old man with pulmonary squamous cell carcinoma underwent an apparently uncomplicated lung lobectomy. His hemodynamics was unremarkable throughout the surgery and initially in the Post-Anesthesia Care Unit...

Acute idiopathic sudden sensorineural hearing loss (ISSNHL) following lumbar spinal surgery is an exceedingly rare phenomenon. This paper presents a case of ISSNHL presenting acutely after lumbar spine decompression and fusion treated with transtympanic steroids and hyperbaric oxygen (HBO₂) therapy. It also presents the ironic case of SSNHL secondary to presumed viral pathology sustained by the patient's operative surgeon who was treated with transtympanic steroids and HBO₂ as well. Proposed etiologies of the patient's ISSNHL include: hypotension, prone operative position, malfitted/malpositioned headrest, microemboli from a cell-saver, and nitrous oxide anesthesia...

Intravenous ketamine is known to inhibit postoperative shivering; however, at present, there has been little research on whether this effect may be achieved with epidural application. The aim of the present study was to evaluate the efficacy and safety of epidural ketamine as a prophylactic agent to prevent shivering in patients undergoing caesarean section during combined spinal-epidural anesthesia. A prospective, randomized, double-blind study was performed. A total of 60 patients who were undergoing elective caesarean section under combined spinal-epidural anesthesia and had an American Society of Anesthesiologists physical status of I or II were recruited...

Although postoperative renal dysfunction is relatively rare after cesarean delivery, preeclampsia is considered as the high-risk population. On the other hand, hydroxyethyl starch (HES) administration for preventing maternal hypotension induced by spinal anesthesia for cesarean delivery is a common practice. However, the effect of HES administration during cesarean delivery on postoperative kidney function in parturients with severe preeclampsia is not well investigated. We retrospectively reviewed both medical and anesthesia records of patients with severe preeclampsia who underwent cesarean delivery from January 2011 to December 2013...

The central administration of glucagon-like peptide-2 (GLP-2) decreases blood pressure in rats. In the present study, we investigated the hypotensive effects of GLP-2 using spontaneously hypertensive rats (SHRs), an animal model of hypertension. The central administration of GLP-2 (0.6 μg) decreased mean arterial pressure (MAP) in SHRs (-24.1 ± 4.5%; P < 0.05), but not in normotensive Wistar-Kyoto (WKY) rats (-10.6 ± 7.4%; P > 0.05), whereas GLP-2 (6 μg) decreased MAP in WKY rats (-23...

We report a case of sudden shock during caesarean section under combined spinal epidural anesthesia. The patient was a 29-year-old woman. During the operation vital signs had been almost stable until a female-baby was born. But after the delivery of the placenta, the patient developed an episode of coughing and dyspnea followed by unconsciousness and bradycardia. She was given adrenaline and intubated, appearing ventricular fibrillation on a EKG. Cardiopulmonary resuscitation was immediately started and sinus rhythm returned...

The recent adoption of an improved lymphatic access technique coupled with Dynamic Contrast-enhanced Magnetic Resonance Lymphangiography has introduced the ability to diagnose and treat severe lymphatic disorders unresponsive to other therapies. All pediatric patients presenting for lymphatic procedures require general anesthesia presenting challenges in managing highly morbid and comorbid conditions both from logistical as well as medical aspects. General anesthesia is used because of the procedural requirement for immobility to accurately place needles and catheters, treat pain secondary to contrast and glue injections, and to accommodate additional procedures...

INTRODUCTION: Spinal anesthesia for cesarean delivery is associated with high incidence of hypotension and is most often prevented by a prophylactic phenylephrine infusion (PPI). In this study, we aimed to identify maternal hemodynamic changes both intraoperatively and postoperatively with the use of the NICaS noninvasive cardiac output monitor in healthy singleton parturients undergoing cesarean delivery (CD) with spinal anesthesia and PPI. METHODS: Healthy term women undergoing spinal anesthesia for singleton CD were enrolled...

Compromised perfusion due to ligation of arteries and veins in esophagectomy with gastric tube reconstruction often (5-20%) results in necrosis and anastomotic leakage, which relate to high morbidity and mortality (3-4%). Ephedrine is used widely in anesthesia to treat intraoperative hypotension and may improve perfusion by the increase of cardiac output and mean arterial pressure (MAP). This study tests the effect of ephedrine on perfusion of the future anastomotic site of the gastric conduit, measured by laser speckle contrast imaging (LSCI)...
