Effect of sevoflurane versus desflurane on blood glucose level in patients undergoing intracranial neurosurgery: A randomised controlled study.

Background and Aims: Anaesthetic agents can affect the neuroendocrine response to surgical stress. Along with affecting other parameters, this can affect blood glucose levels. This study aimed to compare the effect of sevoflurane and desflurane on hourly intraoperative blood glucose levels in non-diabetic patients undergoing intracranial surgery. Methods: A total of 70 adults (18-65 years) of American Society of Anesthesiologists physical status I and II undergoing elective intracranial surgery for supratentorial and infratentorial lesions were enroled. Patients were randomised to receive either sevoflurane or desflurane as the maintenance anaesthetic agent. The blood glucose level was measured hourly after induction until the completion of surgery. Parametric tests, non-parametric tests, Friedman test, generalised estimating equations, Chi-square test, and Fisher's exact test were used to analyse the data. Results: In the sevoflurane group, the mean (standard deviation) blood glucose (mg/dL) increased from 93.34 (9.33) at the baseline to a maximum of 102.00 (8.61) at the 9 hours timepoint. This change was statistically significant (P < 0.001). In the desflurane group, the mean blood sugar (mg/dL) increased from 89.34 (9.85) at the baseline to a maximum of 92.37 (9.92) at the 4 hours timepoint and then decreased to 88.50 (0.71) at 9 hours timepoint. Conclusion: Desflurane caused an initial rise followed by a decline, whereas a gradual increase in intraoperative blood glucose level was seen with sevoflurane use in non-diabetic adult patients undergoing elective neurosurgery. The intraoperative change in blood sugar was statistically significant but was within the normal clinical range.

Perioperative Management of a Child with Klippel-Feil Syndrome and Severe Uncorrected Aortic Stenosis Undergoing Cervical Spine Stabilization.

Severe stenotic aortic valve poses serious anesthetic challenges because of the fixed cardiac output and complex hemodynamics. The challenges magnify in the presence of a difficult airway which not only puts the airway at risk but also disturbs the hemodynamics, which can negatively impact the patient outcome. Moreover, prone positioning, intraoperative hemodynamics, recovery, and extubation are equally challenging for management. This case report highlights the perioperative management of a child with severe uncorrected aortic stenosis and Klippel-Feil syndrome posted for cervical spinal stabilization under anesthesia.

Perioperative Management of a Patient with Chin-On-Chest Deformity Presenting for Reconstructive Spine Surgery.

Chin-on- chest deformity is not uncommon sequelae of ankylosing spondylitis. Apart from difficult airway, several other considerations might include co-existing cardio-respiratory embarrassment, osteoporotic bones, and neurological perturbations. We describe the successful anesthetic management of a case of chin-on-chest deformity with no access to midline neck structures and extremely difficult airway posted for corrective spine surgery.

Impact of Continuous Education and Training in Reduction of Central Line-associated Bloodstream Infection in Neurointensive Care Unit.

BACKGROUND: Patients in the neurointensive care unit have high utilization of devices, thereby increased chance of getting device-associated infection (DAI). Central line-associated bloodstream infection (CLABSI) remains one of the most important DAI. Education remains an important part of the hospital infection control and improves the infection-control practices. MATERIALS AND METHODS: To evaluate the effectiveness of a quality initiative in reducing incidence of CLABSI, a prospective study (January 2017-December 2018) was done estimating CLABSI incidence before and after the intervention. Continuous teaching and training for hand hygiene practice and central-line catheter hub care were used as the tool for this study. RESULTS: The quality improvement (QI) initiative achieved a 48% reduction in the CLABSI rate from the baseline rate of 8.7 to 4.5 per 1000 catheter days. The overall mortality showed a reduction from 1.5 to 0.05% during the post-intervention period. There was a significant improvement in compliance with the hand hygiene practice and catheter hub care in the post-intervention period. DISCUSSION AND CONCLUSION: This study demonstrates adherence to hand hygiene and catheter hub care with continuous teaching, training, and supervision was highly effective in reducing the CLABSI rate. CLINICAL SIGNIFICANCE: Central line-associated bloodstream infection is one of the most important DAI causing significant morbidity and mortality in critically ill patient. Our findings support that continuous educational intervention of hand hygiene with and training on the catheter hub care are two most important preventive measures in the reduction of CLABSI incidence.

Early Post-operative Hemodynamic Perturbation Associated with Topiramate-induced Metabolic Acidosis: A Case Report.

Topiramate is a potent antiepileptic drug with multiple modes of action including inhibition of carbonic anhydrase activity. Inhibition of this enzyme predisposes to non-anion gap metabolic acidosis which has been amply described in the literature. However, the severity is yet to be well defined. We encountered a case of topiramate-induced non-anion gap metabolic acidosis associated with hemodynamic perturbations in an 8-year-old child in the postoperative period.

Anesthetic management in a patient of autosomal dominant polycystic kidney disease with end stage renal disease undergoing endovascular coiling for multiple intracranial aneurysms.

A 27-year-old woman of autosomal dominant polycystic kidney disease presented with multiple intracranial aneurysms at anterior communicating artery and left middle cerebral artery bifurcation. She was undergoing hemodialysis every alternate day and was waiting for a renal transplantation. Endovascular coiling of both these aneurysms was performed under general endotracheal anesthesia. During the procedure special precaution was taken with regard to intra-procedural fluid management and maintenance of cerebral perfusion pressure. The procedure remained uneventful during which a stable hemodynamics was maintained. In this report, the implication of intraprocedural fluid infusion by the neuroradiologist its possible influence on overall anesthetic management has been described.

Video laryngoscope: A boon for airway management in severe facial trauma.

Anaphylactic reaction after autologous blood transfusion: A case report and review of the literature.

Autologous blood transfusion as a cause of intraoperative anaphylaxis is very rare. We encountered one such life-threatening event in a 72-year-old patient undergoing laminectomy and pedicle screw fixation. The probable cause identified was the floseal mixed autologous blood transfusion. Review of literature has been done, and measures to avoid such an event in the future are discussed.

Comparison of intraoperative brain condition, hemodynamics and postoperative recovery between desflurane and sevoflurane in patients undergoing supratentorial craniotomy.

BACKGROUND: Post operative recovery has been reported to be faster with desflurane than sevoflurane anesthesia in previous studies. The use of desflurane is often criticized in neurosurgery due to the concerns of cerebral vasodilation and increase in ICP and studies comparing desflurane and sevoflurane in neurosurgey are scarce. So we compared the intraoperative brain condition, hemodynamics and postoperative recovery in patients undergoing elective supratentorial craniotomy receiving either desflurane or sevoflurane. MATERIALS AND METHODS: Fifty three patients between 18-60yr undergoing elective supratentorial craniotomy receiving N2O and oxygen (60%:40%) and 0.8-1.2 MAC of either desflurane or sevoflurane were randomized to group S (Sevoflurane) or group D (Desflurane). Subdural intra cranial pressure (ICP) was measured and brain condition was assessed.. Emergence time, tracheal extubation time and recovery time were recorded. Cognitive behavior was evaluated with Short Orientation Memory Concentration Test (SOMCT) and neurological outcome (at the time of discharge) was assessed using Glasgow Outcome Score (GOS) between the two groups. RESULTS: The emergence time [Group D 7.4 ± 2.7 minutes vs. Group S 7.8 ± 3.7 minutes; P = 0.65], extubation time [Group D 11.8 ± 2.8 minutes vs. Group S 12.9 ± 4.9 minutes; P = 0.28] and recovery time [Group D 16.4 ± 2.6 minutes vs. Group S 17.1 ± 4.8 minutes; P = 0.50] were comparable between the two groups. There was no difference in ICP [Group D; 9.1 ± 4.3 mmHg vs. Group S; 10.9 ± 4.2 mmHg; P = 0.14] and brain condition between the two groups. Both groups had similar post-operative complications, hospital and ICU stay and GOS. CONCLUSION: In patients undergoing elective supratentorial craniotomy both sevoflurane and desflurane had similar intra-operative brain condition, hemodynamics and post operative recovery profile.
