It can be asymptomatic or if present in more volumes can cause symptoms such as lethargy, headache, confusion, or even severe neurological deficit. Treatment of pneumocephalus with supplemental oxygen via facemask is a common neurosurgical practice. There is not much evidence of use of high-flow nasal oxygen therapy (HFNOT) for the management of PNC. Here we report a case of an 8-year-old boy with postoperative symptomatic pneumocephalus, which resolved with the application of supplemental oxygen via a high-flow nasal cannula with 30 L/min flow and FiO 2 of 0.7 over 72 hours. High-flow nasal oxygen therapy can be an effective modality of treatment for postoperative PNC with added advantages of patient comfort and maintenance of warmth and moisture of the respiratory tract.","PeriodicalId":16574,"journal":{"name":"Journal of Neuroanaesthesiology and Critical Care","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-06-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44314494","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Common methods include somatosensory-evoked potentials (SSEPs) and transcranial motor-evoked potentials (TcMEPs), which have been shown to have a high diagnostic accuracy in detecting new neurological deficits postoperatively. Sequential compression devices (SCDs) are a common method for thromboprophylaxis in spine surgery and are not known to have many device-related complications. To date, there have been no reports of lower extremity ischemia secondary to SCD deflation failure detected by multimodality neuromonitoring during minimally invasive posterior spine surgery. We, therefore, present a case report of an 18-year-old male with adolescent idiopathic scoliosis who underwent minimally invasive posterior spinal fusion with instrumentation. Intraoperative decrease in SSEPs and TcMEPs were noted in the left leg shortly after incision before any instrumentation or reduction occurred. Further examination revealed that the left leg was hypoperfused compared with the right leg and that the left SCD was not properly deflating. Bilateral SCDs were removed, and perfusion and neuromonitoring returned to baseline immediately. Bilateral SCDs and the machine were replaced, and neuromonitoring remained within normal limits for the rest of the surgery. The patient had no postoperative neurologic or vascular deficits. Early detection of lower extremity ischemia by neuromonitoring resulted in the prompt identification and addressing of SCD malfunction, sparing devastating neurological and vascular injury to the patient's leg. This case reinforces the importance of neuromonitoring within spine surgery.","PeriodicalId":16574,"journal":{"name":"Journal of Neuroanaesthesiology and Critical Care","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-05-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49365911","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Several studies have identified potential risk factors for developing hyperlactatemia in neurosurgical patients, including body mass index, surgery duration, tumour volume, and certain drugs such as volatile anesthetic agents and corticosteroids. This systematic review and meta-analysis examined the evidence of the association between perioperative lactate levels in patients undergoing brain surgery and postoperative morbidity and mortality. Methods Using PubMed, Scopus, Web of Science, Embase, CINAHL, Medline, Google Scholar, and the Cochrane Central Register of Controlled Trials databases, a systematic literature search was conducted for studies examining the association between perioperative hyperlactatemia and postoperative outcomes in patients undergoing brain surgery. Two authors independently evaluated the full-text papers for eligibility, and then data extraction and meta-analyses of similar studies were conducted (using a random effect model for each outcome measure). The Newcastle Ottawa Scale was used to evaluate the risk of bias (NOS scale). Results Seven observational studies were included, and a total of 1,832 patients were assessed in the systematic review and meta-analysis. The quality of the included studies ranged from poor to high quality according to the NOS quality assessment tool. Meta-analysis results revealed no significant association between perioperative hyperlactatemia and postoperative new neurological deficits (five studies: odds ratio [OR] = 0.97, 95% confidence interval [CI] [0.50–1.87], p = 0.92; heterogeneity: I 2 = 38%, p = 0.18). Similarly, perioperative hyperlactatemia was neither significantly associated with increased 30-day postoperative mortality (two studies; OR = 0.20, 95% CI [0.02–2.00], p = 0.17; heterogeneity: I 2 = 0%, p = 0.59) nor 6 months survival rate (three studies; OR = 1.05, 95% CI [0.75–1.47], p = 0.79; heterogeneity: I 2 = 0%, p = 0.51). Moreover, there was no difference in the length of hospital stay between the two groups (four studies: mean difference = –0.85, 95% CI [–1.73 to 0.03], p = 0.06). Pooled studies were not homogenous ( I 2 = 68%, p = 0.03). Conclusion Perioperative hyperlactatemia is benign in neurosurgical patients and is not associated with significant postoperative outcomes, such as developing new postoperative neurological deficit, 30-day mortality, 6-month survival, or prolonged hospital stay.","PeriodicalId":16574,"journal":{"name":"Journal of Neuroanaesthesiology and Critical Care","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-05-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44230176","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, development of DI following aneurysmal subarachnoid hemorrhage (SAH) is rarely reported. We describe here a case of intraoperative DI in a patient undergoing aneurysmal clipping surgery that posed a challenge for both diagnosis and management. A 55-year-old female, diagnosed with SAH due to ruptured left middle cerebral artery (MCA) aneurysm, was posted for aneurysmal clipping. A preoperative sudden rebleeding led to neurological deterioration and patient was taken up for the evacuation of hematoma and aneurysmal clipping. Intraoperatively, 2 hours into surgery, polyuria (700–1,000 mL/hour) was noted. Arterial blood gas analysis revealed severe hypernatremia with increased serum osmolality and urine-specific gravity showed hypo-osmolar urine. Possibility of mannitol induced diuresis, overzealous administration of intravenous fluid, and other causes of DI were ruled out. Medical management of DI was initiated and after 45 minutes, urine output was reduced and serum sodium measurements showed decreasing trend indicating responsiveness to treatment. Postoperatively noncontrast computed tomography head showed temporal bleeding with MCA infarct, infarct in thalamic, and hypothalamic region with hydrocephalus. Intraoperative development of central DI was attributed to the evolving ischemic injury to the hypothalamus at the time of rebleeding that was not apparent in preoperative scan. DI resolved postoperatively after 18 hours of medical management. Development of DI during aneurysmal surgery was unexpected and unanticipated. The cause of intraoperative DI was found to be pre-existing ischemic injury of hypothalamic region that subsequently evolved to infarct which was not evident in preoperative scan. A careful observation of preoperative scans and vigilant monitoring may help in early diagnosis and management of such complication in perioperative period.","PeriodicalId":16574,"journal":{"name":"Journal of Neuroanaesthesiology and Critical Care","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-04-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44510505","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
