INTRODUCTION: Endoscopic discectomy and fusions have been gaining popularity in the recent past and are noted to be safe for its application in elderly population. It involves ultra-small incision for discectomy followed by placement of percutaneous screws in awake patients. Treatment of advanced spinal pathology using endoscope-assisted techniques are challenging. Although not common with endoscopic approach, post-operative infection can be problematic as there are no established guidelines on its management...

BACKGROUND: Mini craniotomy for chronic subdural hematoma (CSDH) is associated with lower recurrence rates. However, the procedure is mostly performed under general anesthesia (GA) and therefore frequently requires intensive care unit (ICU) facility, especially in the elderly population. Due to unavailability of ICU beds, and to avoid GA, we started to perform this procedure under local anesthesia (LA). MATERIALS AND METHODS: This was a retrospective medical chart review conducted in the section of Neurosurgery at the Aga Khan Hospital in Karachi, Pakistan...

REVIEW
Christopher McPherson, Terrie Inder
Optimal obstetric and neonatal care requires the provision of adequate analgesia for painful procedures. However, anesthetic and analgesic agents have the potential to adversely impact the developing fetal/neonatal brain. In this setting, clinicians must assess the risks and benefits of pharmacologic anesthesia and analgesia for specific indications in this population. General anesthesia is required for non-obstetric surgery and cesarean section in the absence of neuraxial anesthesia for the health of the mother and fetus...

BACKGROUND AND OBJECTIVE: In this paper, we propose the use of an event-based control strategy for the closed-loop control of the depth of hypnosis in anesthesia by using propofol administration and the bispectral index as a controlled variable. METHODS: A new event generator with high noise-filtering properties is employed in addition to a PIDPlus controller. The tuning of the parameters is performed off-line by using genetic algorithms by considering a given data set of patients...

Previous tracheal surgeries were performed under tracheal and cross-field intubation. However, the intubation would lead to bleeding if the tumors were large or hemorrhagic. Moreover, the tracheal intubation might interfere the surgical vision and anastomosis during the reconstruction process. Therefore, we performed a tracheal tumor resection and reconstruction via nonintubated spontaneous anesthesia. We describe the feasibility and safety of tracheal surgeries via such anesthesia.

It is recommended that endotracheal cuff (ETTc) pressure be between 20 and 30 cm H2O. In this present study, we intend to observe average cuff pressure values in our clinic and the change in these values after the training seminar. The cuff pressure values of 200 patients intubated following general anesthesia induction in the operating theatre were measured following intubation. One hundred patients whose values were measured before the training seminar held for all physician assistants, and 100 patients whose values were measured after the training seminar were regarded as Group 1 and Group 2, respectively...

BACKGROUND: Laparoscopic cholecystectomy (LC) for symptomatic gallstone disease is one of the most common surgical procedures. Concomitant common bile duct (CBD) stones are detected with an incidence of 4-20% and the ideal management is still controversial. The frequent practice is to perform endoscopic sphincterotomy pre-operatively (POES) followed by LC, to allow subsequent laparoscopic or open exploration if POES fails. However, POES has shown different drawbacks such as need for two hospital admissions, need of two anesthesia inductions, higher rate of pancreatitis, and longer hospital stay...

Anaesthesia is often a necessary step when studying insects like the model organism Drosophila melanogaster. Most studies of Drosophila and other insects that require anaesthesia use either cold exposure or carbon dioxide exposure to induce a narcotic state. These anaesthetic methods are known to disrupt physiology and behavior with increasing exposure, and thus ample recovery time is required prior to experimentation. Here, we examine whether two halogenated ethers commonly used in vertebrate anaesthesia, isoflurane and sevoflurane, may serve as alternative means of insect anaesthesia...

BACKGROUND: Endovascular coil embolization and craniotomy with clip ligation are the two most commonly used treatments for ruptured cerebral aneurysm. While coiling maintains the advantages of brevity and complete avoidance of brain retraction and manipulation, clipping offers the benefits of decompression of the injured brain and lower aneurysm recurrence rates. A combined, immediately sequential treatment strategy for acutely ruptured cerebral aneurysm that simultaneously maximizes the advantages of both techniques, while minimizing their respective disadvantages, may be a useful paradigm...

(+)-Dehydrofukinone (DHF), isolated from Nectandra grandiflora (Lauraceae) essential oil, induces sedation and anesthesia by modulation of GABAa receptors. However, no study has addressed whether DHF modulates other cellular events involved in the control of cellular excitability, such as seizure behavior. Therefore, the aim of the present study was to investigate the effect of DHF on cellular excitability and seizure behavior in mice. For this purpose, we used isolated nerve terminals (synaptosomes) to examine the effect of DHF on the plasma membrane potential, the involvement of GABAa receptors and the downstream activation of Ca(2+) mobilization...

Laryngeal cancer was a well known entity since antiquity and its treatment evolved through several phases. The lack of knowledge in anatomy and pathology as well as the absence of anesthesia and proper instrumentation made the treatment almost impossible. Ancient physicians were performing laryngotomy or tracheotomy in an attempt to prevent the suffocation symptoms produced by tumoral masses. In 19th century the invention of laryngoscope and the advent of pathology and anesthesiology encouraged surgeons to operate on man...
