Aim: The hemodynamic response to mouse systemic anaphylaxis is characterized by an initial hypertension followed by sustained hypotension. However, the defense mechanisms of the sympathetic nervous system against this circulatory disturbance is not known. Here, we investigated the renal sympathetic nerve activity (RSNA) response to mouse systemic anaphylaxis, along with the roles of carotid sinus baroreceptor, vagal nerves and the transient receptor potential vanilloid type 1 channel (TRPV1). Methods: Male ovalbumin-sensitized C57BL/6N mice were used under pentobarbital anesthesia...

BACKGROUND: Postherpetic neuralgia (PHN) is the most common and refractory complication of herpes zoster (HZ). Aggressive treatment of acute pain in HZ has the potential to prevent the development of PHN, but the preventive efficacy of supplemental therapy commonly used in clinical practice is controversial. OBJECTIVES: Our aim is to examine the efficacy of supplemental therapy in preventing PHN. STUDY DESIGN: A meta-analysis. SETTING: All of the selected studies are randomized controlled trials (RCTs)...

Laparoscopic surgery is normally performed under general anesthesia, but regional techniques like thoracic epidural and lumbar spinal have been emerging and found beneficial. We performed a clinical case study of segmental thoracic spinal anaesthesia in a healthy patient. We selected an ASA grade I patient undergoing elective laparoscopic cholecystectomy and gave spinal anesthetic in T10-11 interspace using 1 ml of bupivacaine 5 mg ml(-1) mixed with 0.5 ml of fentanyl 50 μg ml(-1). Other drugs were only given (systemically) to manage patient anxiety, pain, nausea, hypotension, or pruritus during or after surgery...

BACKGROUND: The optimal approach to sedation for pleuroscopy remains undefined. Propofol is the favored sedative-hypnotic for many proceduralists but has a narrow therapeutic window and the risk for oversedation is high. Propofol-based sedation administered by anesthesiologists and the routine use of end-tidal capnography and bispectral index (BIS) monitoring may attenuate risks of complications. OBJECTIVES: The purpose of our study was to evaluate the safety and efficacy of monitored anesthesia care for pleuroscopy...

BACKGROUND: In patients with ventricular tachycardia/fibrillation (VT/VF) electrical storm (ES) undergoing catheter ablation (CA), hypotension due to refractory VT/VF, use of anesthesia and cardiac stunning due to repeated ICD shocks might precipitate acute hemodynamic decompensation (AHD). OBJECTIVE: We evaluated the outcomes of emergent cardiopulmonary support with extracorporeal membrane oxygenation (ECMO) to rescue AHD in patients undergoing CA of ES. METHODS: Between 2010 and 2016, 21 patients with ES (VT in 11 and PVC-triggered VF in 10) were referred for CA and had periprocedural AHD requiring emergent ECMO support...

Warwick D Ngan Kee
BACKGROUND: Norepinephrine has been investigated as a potential alterative to phenylephrine for maintaining blood pressure during spinal anesthesia for cesarean delivery with the advantage of less depression of maternal heart rate and cardiac output. However, the relative potencies of these two vasopressors have not been fully determined in this context. METHODS: In a random-allocation, graded dose-response study, 180 healthy patients undergoing spinal anesthesia for elective cesarean delivery received a single bolus of norepinephrine in one of six different doses ranging from 4 to 12 µg or phenylephrine in one of six different doses ranging from 60 to 200 µg to treat the first episode of hypotension...

BACKGROUND: Intraoperative nausea and vomiting (IONV) or postoperative nausea and vomiting (PONV) affecting women undergoing regional anesthesia for cesarean section is an important clinical problem since these techniques are used widely. There are burdens of literature about IONV/PONV and several in parturient and cesarean. However, it needs more attention. The underlying mechanisms of IONV and PONV in the obstetrical setting mainly include hypotension due to sympathicolysis during neuraxial anesthesia, bradycardia owing to an increased vagal tone, the visceral stimulation via the surgical procedure and intravenously administered opioids...

Moyamoya disease is a rare progressive cerebral arteriopathy associated with risk of ischemic and hemorrhagic brain complications. The dental care of affected individuals should be performed in a pain- and stress-free manner to decrease the chance of occurrence of episodes of hypocapnia, hypercapnia, hypotension, hypovolemia, and hypothermia. Dental treatment may be provided in an outpatient dental setting or in a hospital setting, but both venues require interdisciplinary collaboration to ensure safe delivery of patient care...
