Red cell distribution width and Glasgow coma scale score as predictors of in-hospital mortality in maintenance hemodialysis patients diagnosed with spontaneous intracerebral hemorrhage

Glasgow Coma Scale (GCS) score is being widely used as a useful predictor to investigate patients with head injury. High red cell distribution width (RDW) values have been independently associated with mortality and poor neurological outcome. However, there are few data available for Spontaneous Intracerebral Hemorrhage (SIH) in maintenance hemodialysis (MHD) patients. This study aimed to evaluate the prognostic value of the combined measurement of RDW and GCS score in MHD patients with SIH. We retrospectively studied 46 MHD patients who was admitted to our hospital for nontraumatic SIH from October 2014 to May 2020. Data including demographic information, cause of renal failure, comorbidities at ESRD, clinical and laboratory parameters at admission were collected from medical records. Univariate and multivariate Logistic regression analysis were performed to identify independent risk factors of the in-hospital Mortality in Hemodialysis Patients with SIH. The receiver operating characteristic curve (ROC) and areas under the curve (AUCs) were determined. The sensitivity and specificity of independent risk factors were calculated for a range of different cutoff points. A total of 46 patients were enrolled in the study. The in-hospital mortality rate was 69.57%. We divided subjects into 2 groups based on the clinical outcomes. Compared with survivors (n = 14), non-survivors (n = 32) had longer hemodialysis vintage (P = .017), lower GCS score (P < .001), higher hemoglobin (Hb) (P = .032) and RDW (P = .009). In multivariate logistic regression analysis, GCS score (OR 0.719, 95% CI 0.546-0.946; P = .018) and RDW (OR 4.549, 95% CI 1.243-0.946; P = .018) were independent risk factors of in-hospital mortality in MHD patients with SIH. The area under the ROC curve (AUC) for GCS score was 0.849 (95% CI 0.729-0.970) while that for RDW was 0.743 (95% CI 0.596-0.891). The AUC for the combined prediction was 0.916 (95% CI 0.828-1.000), with a sensitivity of 90.63% and a specificity of 88.46%. In conclusion, high RDW and low GCS score were useful and independent poor prognostic markers for in-hospital mortality of MHD patients with SIH.     

Immediate improvement in GCS following needle aspiration of bilateral traumatic subdural effusion in a child in emergency room

A minor head injury can cause traumatic subdural effusion in a child. They often present to pediatric emergencies initially, and there is a delayed referral to neurosurgery. In the emergency room, they should undergo subdural effusion needle aspiration, which can result in an immediate improvement in GCS.     

Emergency protocol in the dental clinic: Assessing medical emergency training requirements and guidelines for dentists

BackgroundMedical emergencies are an unavoidable reality affecting dental practices. This review synthesizes and examines the guidelines offered by governmental and professional organizations.Types of Studies ReviewedLicensing agencies and professional associations were chosen as organizations of focus based on legal authority, high professional regard, or both. International and interprofessional organizational counterparts were chosen as points of comparison. In total, 11 organizations were examined. Guidelines reported were compiled by examination of documents published on official agency websites and in associated peer-reviewed journals.ResultsGuidelines for the handling of medical emergencies in the dental clinic vary in level of detail and scope among sources. Licensing agencies provide basic requirements for training, encouraging oral health care providers to develop and integrate their own emergency response plans. Professional associations provide extensive detail on instruction in medical emergency management. Both licensing agencies and professional associations provide lists of emergency medications and equipment, with varying levels of instruction on drug maintenance and organization. Professional associations emphasize regular review of training and office emergency drills.ConclusionOral health care professionals are provided with basic and required elements of medical emergency training by licensing agencies. They may seek out recommended, but not required, instruction from professional associations. Although guidance is provided, literature on protocol instituted in dental practices is limited. Further research is necessary to determine the oral health care community’s approach to emergency management.Practical ImplicationsProviders must be prepared to handle medical emergencies that they encounter. Accessible and understandable guidelines are crucial to safe dental practice.     

Interictal respiratory variability predicts severity of hypoxemia after generalized convulsive seizures

Objective

Severe respiratory dysfunction induced by generalized convulsive seizures (GCS) is now thought to be a common mechanism for sudden unexpected death in epilepsy (SUDEP). In a mouse model of seizure-induced death, increased interictal respiratory variability was reported in mice that later died of respiratory arrest after GCS. We studied respiratory variability in epilepsy patients as a predictive tool for severity of postictal hypoxemia, a potential biomarker for SUDEP risk. We then explored the relationship between respiratory variability and central CO₂ drive, measured by the hypercapnic ventilatory response (HCVR).

Methods

We reviewed clinical, video-electroencephalography, and respiratory (belts, airflow, pulse oximeter, and HCVR) data of epilepsy patients. Mean, SD, and coefficient of variation (CV) of interbreath interval (IBI) were calculated. Primary outcomes were: (1) nadir of capillary oxygen saturation (SpO₂) and (2) duration of oxygen desaturation. Poincaré plots of IBI were created. Covariates were evaluated in univariate models, then, based on Akaike information criteria (AIC), multivariate regression models were created.

Results

Of 66 GCS recorded in 131 subjects, 30 had interpretable respiratory data. In the multivariate model with the lowest AIC value, duration of epilepsy was a significant predictor of duration of oxygen desaturation. Duration of tonic phase and CV of IBI during the third postictal minute correlated with SpO₂ nadir, whereas CV of IBI during non-rapid eye movement sleep had a negative correlation. Poincaré plots showed that long-term variability was significantly greater in subjects with ≥200 s of postictal oxygen desaturation after GCS compared to those with <200 s desaturation. Finally, HCVR slope showed a negative correlation with measures of respiratory variability.

Significance

These results indicate that interictal respiratory variability predicts severity of postictal oxygen desaturation, suggesting its utility as a potential biomarker. They also suggest that interictal respiratory control may be abnormal in some patients with epilepsy.     

Clinical application of 3DSlicer and Sina in minimally invasive puncture drainage of elderly patients with spontaneous intracerebral hemorrhage under local anesthesia

BackgroundDecreased organ function and poor physical compensatory capacity in elderly patients diagnosed with spontaneous intracerebral hemorrhage (ICH) can make surgical treatment procedures challenging and risky. Minimally invasive puncture drainage (MIPD) combined with urokinase infusion therapy is a safe and feasible method of treating ICH. This study aimed to compare the treatment efficacy of MIPD conducted under local anesthesia using either 3DSlicer + Sina application or computer tomography (CT)–guided stereotactic localization of hematomas in elderly patients diagnosed with ICH.MethodsThe study sample included 78 elderly patients (≥ 65 years of age) diagnosed with ICH for the first time. All patients exhibited stable vital signs and underwent surgical treatment. The study sample was randomly divided into two groups, either receiving 3DSlicer+Sina or CT-guided stereotactic assistance. The preoperative preparation time; hematoma localization accuracy rate; satisfactory hematoma puncture rate; hematoma clearance rate; postoperative rebleeding rate; Glasgow Coma Scale (GCS) score after 7 days; and modified Rankin scale (mRS) score 6 months after surgery were compared between the two groups.ResultsNo significant differences in gender, age, preoperative GCS score, preoperative hematoma volume (HV), and surgical duration were observed between the two groups (all p-values > 0.05). However, the preoperative preparation time was shorter in the group receiving 3DSlicer + Sina assistance compared to that receiving CT-guided stereotactic assistance (p-value < 0.001). Both groups exhibited significant improvement in GCS scores and reduction in HV after surgery (all p-values < 0.001). The accuracy of hematoma localization and puncture was 100% in both groups. There were no significant differences in surgical duration, postoperative hematoma clearance rate, rebleeding rate, postoperative GCS and mRS scores between the two groups (all p-values > 0.05).ConclusionsA combination of 3DSlicer and Sina is effective in accurately identifying hematomas in elderly patients with ICH exhibiting stable vital signs, thus simplifying MIPD surgeries conducted under local anesthesia. This procedure may also be preferred over CT-guided stereotactic localization in clinical practice due to its ease of use and accuracy in hematoma localization.
