Ki Ho Chung, Myeong Soo Cho, Hoon Jin
Perioperative hypertension is a phenomenon in which a surgical patient's blood pressure temporarily increases throughout the preoperative and postoperative periods and remains high until the patient's condition stabilizes. This phenomenon requires immediate treatment not only because it is observed in a majority of patients who are not diagnosed with high blood pressure, but also because occurs in patients with underlying essential hypertension who show a sharp increase in their blood pressure. The most common complication following facelift surgery is hematoma, and the most critical risk factor that causes hematoma is elevated systolic blood pressure...

Closed-loop control of anesthesia based on continuous feedback from processed electroencephalography adjusts drug dosing to target a desired depth of hypnosis during dynamic clinical circumstances, freeing the anesthesiologist to focus on more complex tasks. We describe a case of closed-loop control of total intravenous anesthesia in which a sudden loss of blood required immediate intervention. This case illustrates that closed-loop control of drug delivery maintained an appropriate depth of hypnosis during a rapidly changing surgical situation, and that processed electroencephalography may be a useful adjunct indicator for cerebral hypoperfusion...

Propofol is an anesthetic agent suspended in an emulsion system that includes egg yolk lecithin and soybean oil, because of which, there is concern about the use of propofol in patients allergic to these substances. We examined the association between propofol administration and incidence of adverse events in dogs with allergy to egg yolk lecithin and soybean oil. On the basis of the findings of an allergen-specific immunoglobulin E (IgE) test, 14 dogs with high levels (high-IgE group) and 7 dogs with low levels (normal-IgE group) of IgE were selected...

Diabetic patients have increased cardiac complications during surgery, possibly due to impaired autonomic regulation. Anesthesia lowers blood pressure and heart rate (HR), whereas surgical intervention has opposing effects. The interaction of anesthesia and surgical intervention on hemodynamics in diabetes is unknown, despite being a potential perioperative risk factor. We aimed to determine the effect of diabetes on the integrative interaction between hemodynamics, anesthesia, and surgical incision. Zucker type 2 diabetic rats (DM) and their nondiabetic littermates (ND) were implanted with an intravenous port for drug delivery, and a radiotelemeter to measure mean arterial blood pressure (MAP) and derive HR (total n = 50)...

OBJECTIVES: To explore if the mechanism of the voiding dysfunction caused by spinal cord injury in rats can be improved by intravenous administration of the 5-HT2A/2C receptor agonist, DOI, and discuss whether it can be ascribed to serotonin 2A and 2C receptor up-regulation in lumbosacral cord motoneurons. MATERIALS AND METHODS: Female Sprague-Dawley rats were used, which were divided into two groups (Spinal cord injury group VS Normal control group). Under urethane anesthesia, cystometry was performed to examine the variation of urodynamic parameters before and after successive intrathecal administration of various doses of DOI into the lumbosacral cord...

PURPOSE: Morphine is administered intravenously for pain management in the perioperative period. The effect of the inflammatory response to surgery on morphine distribution across the blood-brain barrier (BBB) in humans was investigated. We hypothesized that a graded surgically induced, systemic inflammatory response alters cerebrospinal fluid (CSF) levels of morphine, morphine-3-glucuronide (M3G), and morphine-6-glucuronide (M6G) through a temporary reduction in BBB drug efflux transporter function...

OBJECTIVE The semisitting position of a patient confers numerous advantages in various neurosurgical procedures, but venous air embolism is one of the associated complications of this position. To date, no prospective studies of the relationship between the degree of head elevation and the rate and severity of venous air embolism for patients undergoing a procedure in this position have been performed. In this study, the authors compared changes in the severity of venous air embolism according to the degree of head elevation (30° or 45°) in patients undergoing an elective cranial neurosurgical procedure in the semisitting position...

The optimal approach to postoperative analgesia in patients with bilateral diaphragmatic paralysis undergoing abdominal surgery remains unclear. We report a 69-year-old woman with bilateral diaphragmatic paralysis who underwent a laparoscopic hernia repair and an open laparotomy for reversal of a Hartmann procedure under general anesthesia. Postoperative analgesia was provided by intravenous opioid and epidural local anesthetic and opioid, respectively. The patient's trachea was successfully extubated at the end of both surgical procedures...

REVIEW
Chittaranjan Andrade
Ketamine is a racemic mixture of the enantiomers R-ketamine and S-ketamine (esketamine). S-ketamine has greater analgesic and anesthetic effects than R-ketamine and is less likely to cause psychotomimetic and other adverse effects. There is therefore an emerging interest favoring the use of S-ketamine over racemic ketamine when the drug is used for analgesia or anesthesia. This article examines preclinical and clinical literature on the antidepressant properties of S-ketamine. Animal data suggest potential advantages for R-ketamine over S-ketamine...
