Inadvertent perioperative hypothermia is expected in the elderly during central neuraxial anesthesia. We aimed to compare the incidence of intraoperative hypothermia (< 36-degree celsius) between preoperative forced-air warming for 30 minutes and non-warming groups. Also, we compared the time to develop hypothermia, perioperative shivering, duratio...

Objectives: Percutaneous nephrolithotomy and placement of nephrostomy tube are performed for renal stones >2 cm in diameter. Attempts have been made to infiltrate local anesthetics with or without adjuvants into the surgical site to reduce pain. We hypothesized that there would be a significant prolongation of the analgesic effect of local anesthet...

Electrolyte Imbalance and Fluid Management in Critical Patients:Fluid and electrolyte abnormalities are common in critically ill patients. Inability to diagnose them in time and manage them properly can prove to be disastrous and poorly affect final outcome. In this chapter we review the common electrolyte abnormalities seen in these critically ill...

Neuromonitoring refers to the use of various modalities to monitor the integrity of the nervous system. Unlike the other body systems that have been easy to monitor, evaluation of structural integrity and function of the nervous system has been difficult. However, over last two decades, there has been a significant upward trend in development of ne...

Background: Stellate ganglion block (SGB) causes blockage of sympathetic nerve activity, which may lead to intracerebral vessel dilatation and relieve cerebral vasospasm in patients of aneurysmal subarachnoid hemorrhage (aSAH). Objective: The aim of this study was to evaluate the efficacy and safety of SGB to relieve cerebral vasospasm on clinic...
Article
Background: Studies have evaluated the effects of volatile and intravenous anesthetic agents on the cerebral vasculature with inconsistent results. We used digital subtraction angiography to compare the effects of propofol and sevoflurane on the luminal diameter of cerebral vessels and on cerebral transit time in patients with aneurysmal subarachn...
Chapter
The supratentorial space-occupying lesions (SOLs) in children are mostly composed of intracranial tumors but may also be due to the presence of abscesses, cysts, hematomas, or other lesions. Primary brain tumors are the most common solid tumors in childhood. The brain tumors are considered the second most common malignancy in children after leukemi...
Chapter
Brain injury remains a major source of morbidity associated with congenital heart surgery. In pediatric patients, neurological injury after cardiac surgery may manifest as stroke, postoperative cognitive dysfunction, delirium, or more subtle signs leading to a long-term sequel and neurodevelopmental impairments. These complications may eventually c...
Article
Background The indications for intracranial pressure (ICP) monitoring in patients with acute brain injury and the effects of ICP on patients’ outcomes are uncertain. The aims of this study were to describe current ICP monitoring practises for patients with acute brain injury at centres around the world and to assess variations in indications for IC...

Background: Fluid imbalance is common after aneurysmal subarachnoid hemorrhage and negatively impacts clinical outcomes. We compared intraoperative goal-directed fluid therapy (GDFT) using left ventricular outflow tract velocity time integral (LVOT-VTI) measured by transesophageal echocardiography with central venous pressure (CVP)-guided fluid th...

Background: Electrolyte imbalance and acute diabetes insipidus (DI) are the most common complications in patients undergoing craniopharyngioma excision. Data are sparse regarding the choice of fluid in these patients. We compared the effects of balanced salt solution and 0.45% saline infused perioperatively on serum osmolality and serum sodium lev...

Background Literature shows fentanyl reduces the median effective concentration (EC50) of propofol when used for various noxious stimuli. However, fentanyl combined with propofol has a depressive effect on haemodynamics. We hypothesise that low dose dexmedetomidine will reduce the propofol requirement for induction with better haemodynamic profile...
Article

Intraocular foreign body injuries are a common form of eye trauma in paediatric patients. The fear of losing vision amounts to the anxiety of parents and early retrieval is warranted. In such cases, induction of anaesthesia in view of uncertain Nil Per Oral (NPO) status and an uncooperative child makes the situation more challenging for the anaesth...

Purpose: Oral Triclofos is widely used as a sedative agent in children. However, the role of Triclofos as a sedative agent in children undergoing ophthalmological procedures has not been adequately studied. The aim of this study was to determine the safety and efficacy of oral Triclofos in children suffering from pediatric glaucoma who were underg...

Objective To determine the relationship between various anthropometric parameters (age, weight, neck circumference, head circumference, thyromental distance, sternomental distance, frontal plane to chin distance, and frontal plane to chin distance by weight ratio) in neonates with difficult laryngoscopy and difficult intubation. Design A Prospecti...

Unilateral recurrent pleural effusions are commonly encountered in critical care practice. Relevant clinical history, physical examination, radiology, and diagnostic thoracentesis usually identify the cause of pleural effusion in most cases. Thoracoscopy or video-assisted thoracic surgery may be required in selective cases. We report a case of 32-y...

Background: Traumatic brain injury (TBI) induces major insult to the normal cerebral physiology. The anesthetic agents may infrequently produce deleterious effects and further aggravate damage to the injured brain. This study was conducted to evaluate the effects of propofol and sevoflurane on cerebral oxygenation, brain relaxation, systemic hemod...
Article
Background Acromegaly patients have a very high incidence of difficult endotracheal intubation. The Modified Mallampatti grading (MMPG) in the sitting position is a common test performed preoperatively to predict difficult intubation. It has been suggested that supine MMPG is possibly a better predictor of difficult tracheal intubation (DTI) rather...

Cardiac disease is an important cause of mortality in pregnancy. It has the potential to remain undiagnosed and may present with cardiovascular decompensation during pregnancy, at the time of delivery, or immediately postpartum. It can have long-term implications to the life of the affected women and their families. This review summarises the curre...

Background: Exposure to anesthesia has been postulated to affect the cognitive function by inciting central nervous system inflammation. Hence, we planned to compare the psychometrical effects of anesthetic agents propofol, desflurane, or sevoflurane on postoperative cognitive function and also measure the change in concentration of serum S-100β,...

Background: End-tidal carbon dioxide (PEtCO2) is a noninvasive reliable technique to measure arterial partial pressure of carbon dioxide (PaCO2) in the body under general anesthesia. However, gradient between PaCO2 and PEtCO2 (P[a-Et] CO2) is influenced by many factors. Aims: In the present study, we evaluated the changes in P (a-Et) CO2 for lap...

We describe our experience of management of a young hypertensive male taken up for coiling of an unruptured intracranial aneurysm whom we diagnosed to be a case of coarctation of aorta during preanesthetic check-up. This diagnosis changed the treatment of the patient completely. We report this to emphasize the need to do a thorough preoperative che...

Gamma knife surgery is a type of radiation therapy, which utilizes highly sophisticated equipment to focus around 200 tiny beams of radiation on a tumor or other target with high accuracy. It is primarily used to treat benign brain tumors, craniopharyngiomas, AV malformations, pituitary adenomas, acoustic neuromas, brain metastases, other tumors of...
Article
Tracheostomy tube change is a relatively common procedure once a tracheo-cutaneous tract matures. Regular tracheostomy tube changes prevent the formation of granulation tissue and reduce bacterial colonization (Yaremchuk and Yaremchuk in Laryngoscope 113(1):1–10, 2003). However, serious complications such as subcutaneous emphysema, loss of airway a...
