Objective: We aimed to predict the risk of hypotension due to spinal anesthesia (HSA) by measuring the diameter and area of the inferior vena cava (IVC-D, IVC-A) through ultrasound and pleth variability index (PVI) in patients who underwent endovenous radiofrequency ablation under spinal anesthesia (SA).

Methods: This cross-sectional, observational, and prospective study was completed with 64 patients. Before SA, PVI IVC-D, and IVC-A were measured.

Corpus callosum agenesis develops when the band which connects the two hemispheres of the brain does not occur in utero. It is associated with prenatal infections, genetic factors, toxic exposures, metabolic disorders, and chromosome errors. Mostly seen clinical features are macrocephaly, microcephaly, seizures, motor retardation, hypotonia, eye anomalies, and facial dysmorphisms.

Background: In this prospective, randomized study, we evaluated the intranasal administration of Midazolam ketamine combination, midazolam, and ketamine in premedication for children.

Material And Methods: We studied 60 American Society of Anesthesiology physical status Classes I and II children aged between 1 and 10 years undergoing ear nose throat operations. All cases were premedicated 15 min before operation with intranasal administration of 0.

Leigh syndrome (LS) is a rare disease mainly affecting the central nervous system due to the abnormalities of mitochondrial energy generation and seen in early childhood with progressive loss of movement, mental abilities, seizures, nystagmus, ophthalmoparesis, optic atrophy, ataxia, dystonia, or respiratory failure. Anesthesia and surgery exacerbate the risks of aspiration, wheezing, and breathing difficulties. Tracheal irritability can be stimulated with the efforts of intubation.

Neurofibromatosis type 1 (NF1) is an autosomal-dominant neuroectodermal hereditary disorder, in which spinal skeletal deformities are one of the manifestations. Pectus carinatum, temporomandibular joint dysfunction, and kyphoscoliosis can be seen with this genetic disorder which can lead to cardiorespiratory system problems and can cause difficulty in airway management. We present the anesthetic management of a NF1 patient with a sharp thoracolumbar dystrophic kyphoscoliosis who have been posted for emergency cesarean section as a result of fetal distress.

Regional anesthesia in the form of combined cervical plexus block is gaining popularity as a technique of choice for cervical spine surgeries, especially for urgent ones. An important advantage is that it allows continuous monitoring of patient's neurological status. The success of the block often depends on accurate placement of the local anesthetic.

Persistent hiccup is uncommon, and the mechanism is poorly understood. We present the case of a 43-year-old male patient referred to the Algology department due to chronic back pain who developed what we believe a rare case of persistent hiccup secondary to caudal epidural steroid injection (CESI). The causes of hiccup are many and include electrolyte derangement, nutritional deficiencies, gastrointestinal disorders and instrumentation, cardiovascular disorders, renal impairment, central nervous system disorders, and drugs; however, the cause may be unknown.

Background: The postdural puncture headache (PDPH) and postdural puncture backache (PDPB) are well-known complications of spinal anesthesia. There are some attempts to reduce the frequency of complication such as different design of the spinal needles.

Aims: The primary outcome of this study is to compare the incidence of PDPH between 26-gauge Atraucan and 26-gauge Quincke spinal needles in elective cesarean operations.

Purpose:: To compared the effects of sevoflurane and desflurane on early anesthesia recovery in patients undergoing to craniotomy for intracranial lesions.

Methods:: After IRB approval, the study included 50 patients aged 18-70 years who had ASA physical statuses of I-II and were scheduled for intracranial surgery. Patients were randomly divided into two groups: sevoflurane and desflurane.

Background: Sugammadex offers a good alternative to the conventional decurarisation process currently performed with cholinesterase inhibitors. Sugammadex, which was developed specifically for the aminosteroid-structured rocuronium and vecuronium neuromuscular blockers, is a modified cyclodextrin made up of 8 glucose monomers arranged in a cylindrical shape.

Methods: In this study, the goal was to investigate the efficacy of sugammadex.

Objectives: We aimed to investigate the effectiveness and complications of the percutaneous vertebroplasty (PVP) applications in vertebral compression fractures.

Methods: Our study was carried out as a retrospective study in which PVP was conducted on patients with vertebral compression fractures due to benign or malignant causes between October 2006 and December 2009. The patients' pain was evaluated on a visual analog scale (VAS).

Background: Over the last several decades there has been a general trend toward reduction and minimalization in surgical treatment of chronic back pain, since open surgery brings complications in small and contained disc herniations instead of achieving expected success. Attention has been focussed on percutaneous nucleoplasty due to the limited success of other minimally invasive methods, as well due to their associated complications. However, there have been few studies in the English literature with a follow-up period of more than 1 year.

Background: The unavailability of an effective and long-lasting treatment for sacroiliac-based pain has led researchers to study the efficacy of radiofrequency in denervation. In this study, we aimed to investigate the efficacy and safety of novel cooled radiofrequency application for sacral lateral-branch denervation.

Methods: Patients experiencing chronic sacroiliac pain were selected for our observational study.
