Task-sharing spinal anaesthesia care in three rural Indian hospitals: a non-inferiority randomised controlled clinical trial.

Background: Task-sharing of spinal anaesthesia care by non-specialist graduate physicians, termed medical officers (MOs), is commonly practised in rural Indian healthcare facilities to mitigate workforce constraints. We sought to assess whether spinal anaesthesia failure rates of MOs were non-inferior to those of consultant anaesthesiologists (CA) following a standardised educational curriculum.

Methods: We performed a randomised, non-inferiority trial in three rural hospitals in Tamil Nadu and Chhattisgarh, India.

Mortality in sickle cell disease: A population-based study in an aboriginal community in the Gudalur Valley, Nilgiris, Tamil Nadu, India.

Background: Sickle cell disease (SCD), the most common monogenic disorder, affects more than 300 000 births annually, with 44  000 in India. Although the clinical phenotype of SCD is considered to be milder in aboriginal populations in India, there is a paucity of data on outcomes. To determine the severity of SCD in this population, we studied mortality rates and causes of mortality in a longitudinal cohort of patients with SCD in a remote aboriginal community in India receiving community-based comprehensive care.

Simulation capacity building in rural Indian hospitals: a 1-year follow-up qualitative analysis.

Introduction: The benefits of simulation-based medical training are well described. The most effective way to plant and scale simulation training in rural locations remains undescribed. We sought to plant simulation training programmes for anaesthesia emergencies in two rural Indian hospitals.

Anesthesia for Same Day Discharge After Craniotomy: Review of a Single Center Experience.

Same day discharge or outpatient surgery for intracranial procedures has become possible with the advent of image-guided minimally invasive approaches to surgery and availability of short-acting anesthetic agents. In addition, patient satisfaction and the benefits of avoiding hospital stay have resulted in the evolution of neurosurgical day surgery. We reviewed our experience and the available literature to determine the perioperative factors involved which have promoted and will improve this concept in the future.

Infusion dose requirement of rocuronium in patients on phenytoin therapy - A prospective comparative study.

Background And Aims: Patients with intracranial tumour are usually on anticonvulsants. Patients on phenytoin therapy demonstrate rapid metabolism of nondepolarising muscle relaxants secondary to enzyme induction. Infusion dose requirement of rocuronium in such patients has been sparingly studied.

Comparison of General and Local Anesthesia for Deep Brain Stimulator Insertion: A Systematic Review.

Background: Subthalamic nucleus deep brain stimulation (STN-DBS) has become a standard treatment for many patients with Parkinson's disease (PD). The reported clinical outcome measures for procedures done under general anesthesia (GA) compared to traditional local anesthetic (LA) technique are quite heterogeneous and difficult to compare. The aim of this systematic review and metaanalysis was to determine whether the clinical outcome after STN-DBS insertion under GA is comparable to that under LA in patients with Parkinson's disease.

Perioperative Factors Contributing the Post-Craniotomy Pain: A Synthesis of Concepts.

The perioperative management of post-craniotomy pain is controversial. Although the concept of pain control in non-neurosurgical fields has grown substantially, the understanding of neurosurgical pain and its causative factors in such a population is inconclusive. In fact, the organ that is the center of pain and its related mechanisms receives little attention to alleviate distress during neurosurgical procedures.

Accuracy in Blood Pressure Monitoring: The Effect of Noninvasive Blood Pressure Cuff Inflation on Intra-arterial Blood Pressure Values.

Context: Both invasive and noninvasive blood pressure (invasive arterial blood pressure [IABP] and noninvasive BP [NIBP]) monitors are used perioperatively; however, they often produce different values. The reason for this discrepancy is not clear, and it is possible that the act of cuff inflation itself might affect the IABP values, especially with the recurrent cycling of NIBP cuff.

Aim: The aim of this study was to determine the effect of ipsilateral NIBP cuff inflation on the contralateral IABP values.

Airway adverse events following posterior occipito-cervical spinal fusion.

Management of the airway may be challenging in patients undergoing occipito-cervical spine fusions (OCF). Changes in the occipito-cervical angle (dOC2A) of fusion after surgery may result in acute airway obstruction, dyspnea and/or dysphagia. Objectives of the study were to review the airway management of patients during posterior OCF, determine the incidence, nature and risk factors for postoperative airway adverse events (AEs), and to determine the relationship between airway AEs and the change in dOC2A.

Effect of Hyperoxia on Cerebral Blood Flow Velocity and Regional Oxygen Saturation in Patients Operated on for Severe Traumatic Brain Injury-The Influence of Cerebral Blood Flow Autoregulation.

Background: The effect of normobaric hyperoxia on brain oxygenation in the presence or absence of intact autoregulation has not been studied previously in acute traumatic brain injury (TBI).

Methods: In this prospective clinical investigation of 50 patients operated on for severe TBI, cerebral blood flow (CBF) velocity in the middle cerebral artery was measured using transcranial Doppler. Regional cerebral oxygen saturation using near-infrared spectroscopy at 3 different fractions of inspired oxygen (Fio) (0.

Intra-operative electrooculographic monitoring to prevent post-operative extraocular motor nerve dysfunction during skull base surgeries.

Background And Aims: Intra-operative identification and preservation of extraocular motor nerves is one of the main goals of surgeries for skull base tumours and this is done by monitoring the extraocular movement (EOM). Intra-operative electromyographic monitoring has been reported, but it is a complex and skilful process. Electrooculography (EOG) is a simple and reliable technique for monitoring EOMs.

Pediatric awake craniotomy for seizure focus resection with dexmedetomidine sedation-a case report.

Resection of lesions near the eloquent cortex of brain necessitates awake craniotomy to reduce the risk of permanent neurologic deficits during surgery. There are limited reports of anesthetic management of awake craniotomy in pediatric patients. This report is on use of dexmedetomidine sedation for awake craniotomy in a 11-year-old child, without any airway adjuncts throughout the procedure.

Rare complication of anterior communicating artery aneurysm coiling: Transient retrograde amnesia.

Amnesia is an unusual and rare complication following endovascular coiling of intracranial aneurysms. We present a case of anterior communicating artery (ACOM) aneurysm in which the patient developed retrograde amnesia following endovascular coiling of the aneurysm. On imaging there was infarct involving bilateral fornices.
