An operating room (OR) fire is a rare event but may cause critical harm to patients and health care personnel. We present 2 fire incidents in the rear cabinet of an anesthesia machine, not previously reported in the literature. An anesthesia machine in standby mode is considered safer than in use, but in the first case, the fire occurred while the machine was on standby mode.

 Intraoperative aneurysmal rupture (IAR) is a catastrophic complication; however, its impact on neurological outcome is debatable. We studied the effects of IAR on intraoperative and postoperative complications and neurological outcome.  In this retrospective study, adult patients who underwent aneurysmal clipping over a period of 2 years were divided as follows: group R (with IAR) and group N (without IAR).

Introduction: Stellate ganglion block (SGB) is commonly performed to treat chronic painful conditions, such as complex regional pain syndrome (CRPS) and postherpetic neuralgia. However, whether it is effective in reducing anesthesia and analgesia requirement during surgery (acute pain) is not known.

Materials And Methods: Sixty American Society of Anesthesiologists (ASA) physical status I and II patients with CRPS type II undergoing surgery for repair of brachial plexus injury were randomized (1:1) to receive SGB with either 10 mL of 0.

Major blood loss during neurosurgery can lead to several complications, including life-threatening hemodynamic instabilities. Studies addressing these complications in patients undergoing intracranial tumor surgery are limited. During the study period, 456 patients who underwent elective craniotomy for brain tumor excision were categorized into four groups on the basis of estimated intraoperative blood volume loss: Group A (<20%), Group B (20-50%), Group C (>50-100%), and Group D (more than estimated blood volume).

Background And Aims: Infratentorial neurosurgical procedures are considered high risk for the development of postoperative pulmonary complications (POPCs), prolonging hospital stay of patients with substantial morbidity and mortality.

Material And Methods: Patients between the ages of 18 and 65 years, who underwent elective surgery for posterior fossa tumors over a period of two years, were reviewed. Data including American Society of Anesthesiologists physical status; comorbidities like hypertension, diabetes mellitus and hypothyroidism, history of smoking, obstructive sleep apnea, respiratory symptoms, lower cranial nerve (LCN) palsy; intraoperative complications such as hemodynamic alterations suggestive of brain stem or cranial nerve handling, tight brain as informed by the operating neurosurgeon, blood loss, and transfusion; and postoperative duration of mechanical ventilation, tracheostomy, POPCs, length of ICU and hospital stay, general condition of the patient at discharge, and cause of in-hospital mortality were collected.

Purpose: Chest physiotherapy and tracheal suction cause sympathetic stimulation and increase heart rate (HR), mean arterial pressure (MAP) and intracranial pressure (ICP) which may have deleterious effect in the head injured. We planned to compare the effect of intravenous dexmedetomidine and lidocaine on intracerebral and systemic hemodynamic response to chest physiotherapy (CP) and tracheal suctioning (TS) in patients with severe traumatic brain injury (sTBI).

Methods: Prospective, randomized study in patients with sTBI, 18-60 years of age, undergoing mechanical ventilation and intraparenchymal ICP monitoring.

Surgical excision of meningioma is often complicated by significant blood loss requiring blood transfusion with its attendant risks. Although tranexamic acid is used to reduce perioperative blood loss, its blood conservation effect is uncertain in neurosurgery. Sixty adults undergoing elective craniotomy for meningioma excision were randomized to receive either tranexamic acid or placebo, initiated prior to skin incision.

Abdominal compartment syndrome is a rare entity that can be life-threatening if not diagnosed and correctly managed in time. We report a case of abdominal compartment syndrome following an apparently uneventful excision and repair of myelomeningocele (MMC). Though MMC is the most complex congenital spinal cord malformation compatible with life and early surgery is recommended to decrease the risk of meningitis and sepsis but generally surgery is safe without major perioperative turbulence.

Background: Cognitive dysfunction after subarachnoid hemorrhage (SAH) has been attributable to presence of subarachnoid blood, hydrocephalus (HCP), cerebral edema, vasospasm, and temporary clipping of intracranial aneurysm. Provision of neuroprotection during temporary clipping may improve postoperative cognition in such patients.

Materials And Methods: Good-grade aneurysmal SAH patients undergoing temporary clipping during surgery were allocated either to group C (control) or group P (propofol).

Background And Objectives: To examine the effect of cerebrospinal fluid (CSF) flow during percutaneous retrogasserian glycerol rhizotomy (PRGR) on long term pain relief in patients with trigeminal neuralgia.

Methods: Eighty-nine patients with trigeminal neuralgia underwent 102 PRGR procedures. PRGR was conducted under fluoroscopy.
