Potential side effect of propofol and sevoflurane for anesthesia of anti-NMDA-R encephalitis.

ABSTRACT:

Background

Many anesthetic drugs interact with the NMDA receptor and may therefore alter the clinical presentation of anti-NMDA-R encephalitis.

Case presentation

A 24-year-old woman was admitted to hospital for decreased consciousness and hyperthermia. Cerebrospinal fluid analysis revealed lymphocytic pleocytosis, and elevated protein. Cultures were negative. Patient state worsened with agitation, facial dyskinesia, ocular deviation, and limb dystonia. Diagnosis of anti-NMDA-R encephalitis was evidenced by specific antibodies. High doses of methylprednisolone were administered. CT scan disclosed an ovarian teratoma and tumor resection was scheduled under anesthesia with propofol, sufentanil, atracurium and sevoflurane. Sedation after surgery was maintained with propofol. Rapidly after surgery, patient's condition deteriorated with increase of dyskinesias, and two tonic-clonic generalized seizure events.

Conclusion

In patients with anti-NMDA-R encephalitis, anesthesia using benzodiazepines, opiates and curares, which fail to interfere with the NMDA pathway, should be preferred.

Project description:Background and aimTotal intravenous anesthesia (TIVA) has proven advantage over inhalational anesthesia in terms of stable hemodynamic, eco-friendly, and good recovery profile, but apprehension regarding adequate depth of anesthesia and intraoperative recall is still pertaining. This study aims to compare propofol-dexmedetomidine-based TIVA with sevoflurane-based inhalational anesthesia in modified radical mastectomy in terms of depth of anesthesia, intraoperative recall, recovery profile, and hemodynamic status.Settings and designThis prospective randomized controlled study was conducted at a tertiary care center over a time frame of 1 year.MethodologyIn this randomized controlled study, 100 patients were randomly distributed into two groups: TIVA (Group T) and inhalational anesthesia (Group I). Group T patients received injection dexmedetomidine: 1 μg.kg-1 over 10 min followed by 0.7 μg.kg-1.h-1 and injection propofol: 25-100 μg.kg-1.min-1. Ventilation was maintained with oxygen-air gas flow. In Group I, patients were ventilated with nitrous oxide-oxygen (50:50) and sevoflurane. Rest of anesthesia for both the groups was same. Primary objective was to achieve adequate depth of anesthesia as monitored by intraoperative bispectral index value (BIS, 40-60). Hemodynamic variables, recovery profile, and amount of individual anesthetic agent consumed were recorded for comparison between two groups. For comparison of scale variables between two groups, independent sample t-test for significant difference between two sample means has been followed.ResultsIntraoperative BIS and hemodynamic variables were comparable (P > 0.05). Emergence time was 5.10 min in the TIVA group versus 8.38 min in the inhalational group (P = 0.00). Modified Aldrete score was comparable in two groups (P > 0.05). Cost of TIVA agents consumed per patient was 40% lesser than inhalational agents.ConclusionTIVA maintains adequate depth of anesthesia along with stable hemodynamic and good recovery profile, at low cost in an eco-friendly manner.
