    Airway problems caused by hypogonadism in male patients undergoing neurosurgery
    (ANESTHESIA AND ANALGESIA, 2005)
    Unanticipated difficult endotracheal intubations can pose challenges for the anesthesiologist. Risks include airway injury, hypoxemia, and death. There is intubation difficulty in various conditions including Downs syndrome, achondroplasia, acromegaly, and dwarfism. We describe difficulty in intubating the trachea with an appropriate sized endotracheal tube in two young male patients with hypogonadism presenting for neurosurgical procedures under general anesthesia. We discuss the role of hypogonadism and the effects of gonadotropin hormones on pubertal laryngeal growth in male patients.

    Anesthesia and intracranial arteriovenous malformation
    (NEUROLOGY INDIA, 2004)
    Anesthetic management of intracranial arteriovenous malformation (AVM) poses multiple challenges to the anesthesiologist in view of its complex and poorly understood pathophysiology and multiple modalities for its treatment involving different sub-specialties. The diagnosis of AVM is based on clinical presentation as well as radiological investigation. Pregnant patients with intracranial AVM and neonates with vein of Galen malformation may also pose a,special challenge and require close attention. Despite technological advancement, reported morbidity or mortality after AVM treatment remains high and largely depends on age of the patient, recruitment of perforating vessels, its size, location in the brain, history of previous bleed and post-treatment hyperemic complication. Anesthetic management includes a thorough preoperative visit with meticulous planning based on different modalities of treatment including anesthesia for radiological investigation. Proper attention should be directed while transporting the patient for the procedure. Protecion of the airway, adequate monitoring, and maintaining neurological and cardiovascular stability, and the patient's immobility during the radiological procedures, appreciation and management of various complications that can occur during and after the procedure and meticulous ICU management is essential.

    Bradycardia and sinus arrest following saline irrigation of the brain during epilepsy surgery
    (JOURNAL OF NEUROSURGICAL ANESTHESIOLOGY, 2004)
    Adverse cardiac events during the intraoperative period are life-threatening. The authors report three episodes of severe bradycardia and sinus arrest that occurred in a patient undergoing anterior temporal lobectomy and amygdalo-hippocampectomy for the treatment of epilepsy. The first episode occurred during resection of the amygdala; the other two episodes were observed during subsequent irrigation of the exposed brain structures, most likely the brain stem structures, because of a rent that the surgeon had deliberately made into the basilar cistern for better anatomic appreciation of the structures to be excised. The patient responded well to treatment with no adverse outcomes. The probable mechanisms leading to this event are discussed; the authors excluded insular cortex stimulation, the effects of the anesthetic drugs used, and venous air embolism as a cause of bradycardia and sinus arrest. The amygdala resection was the most likely cause of the first episode of bradycardia; the second episode of bradycardia and sinus arrest occurred because of inadvertent stimulation of brain structures by the high temperature (42degreesC) of the saline used for irrigation. To counter its effects, saline irrigation at room temperature (20degreesC) was started, and this caused the third episode of bradycardia, most likely because of "temperature shock" of the exposed brain. Prompt communication with the surgical team and vigilance are crucial for the appropriate management of such an incident, which may pose a threat to life. Avoiding irrigation of the exposed brain with high-temperature saline may prevent such an incident.

    Effect of lung ventilation with 50% oxygen in air or nitrous oxide versus 100% oxygen on oxygenation index after cardiopulmonary bypass
    (JOURNAL OF CARDIOTHORACIC AND VASCULAR ANESTHESIA, 2006)
    Objective: This study was designed to assess the use of 100% oxygen or 50% oxygen in air or nitrous oxide after cardiopulmonary bypass (CPB) on atelectasis, as evidenced by the oxygenation index (PaO2/F1O2), after coronary artery bypass graft (CABG) surgery.Design: Prospective, randomized clinical study.Setting: University teaching hospital.Participant: Thirty-six adult patients undergoing CABG surgery.Interventions: Patients either received 50% O-2 in air (50% O-2 group), 50% O-2 in N2O (50% N2O group), or 100% O-2 (100% 02 group) after CPB.Measurements and Main Results: Apart from demographic and perioperative clinical data, extubation time, mediastinal drainage, and pulmonary complications were also recorded. After CPB, arterial blood gases done at various time points until 3 hours postextubation and oxygenation index were calculated. No significant differences were noted in demographic and perioperative data except preoperative hemoglobin and fluid use. Significant deterioration in arterial oxygenation was noted in the 100% O-2 group from the baseline value, whereas significant improvement was seen in the 50% O-2 group at 4 time points from baseline value and at all time points from the 100% O-2 group. After initial deterioration in oxygenation, no further change was evident in the 50% N2O group. Furthermore, there was a greater increase in the oxygenation index as compared with the 100% O-2 group. Time to extubation was also longer in the 100% O-2 group than the 50% O-2 group.Conclusion: Significant deterioration in arterial oxygenation and an increase in the extubation time occurred with the use of 100% O-2 after CPB, whereas better oxygenation was evident with the use of 50% O-2 in air.

    Effect of nitrous oxide in reducing pain of propofol injection in adult patients
    (ANAESTHESIA AND INTENSIVE CARE, 2005)
    In a randomized, double-blind, prospective trial we compared the efficacy of pre-treatment with nitrous oxide (with or without premixed lignocaine in propofol) for the prevention of propofol-induced pain. Ninety consecutive patients were recruited in the study and divided into three groups of 30 each, who received either 50% nitrous oxide in oxygen along with lignocaine 40 mg mixed in 1% propofol 20 ml (Group NL), 50% nitrous oxide in oxygen without lignocaine in propofol (Group N), and 50% oxygen in air with lignocaine mixed in propofol 40 mg (Group L). Pain scores were graded on a four point verbal rating scale (0-3). Eighty-nine patients completed the study while one patient developed excitement, agitation and tremor during nitrous oxide in oxygen inhalation. Eleven patients (36.7%) complained of pain in the group L compared to 7 (23.3%), and 1 (3.3%), in groups N and NL respectively [group NL vs group L (P< 0.001) and group NL vs N (P< 0.001)]. There was no statistical difference observed between group N and group L. Inhalation of 50% nitrous oxide reduces pain on propofol injection. The combination of 50% nitrous oxide and lignocaine mixed with propofol was the most effective treatment.
