Neurological outcome of postanoxic refractory status epilepticus after aggressive treatment.

Refractory status epilepticus (RSE) occurs in up to 30% of patients following resuscitation after cardiac arrest. The impact of aggressive treatment of postanoxic RSE on long-term neurological outcome remains uncertain. We investigated neurological outcome of cardiac arrest patients with RSE treated with a standardized aggressive protocol with antiepileptic drugs and anesthetics, compared with patients with other electroencephalographic (EEG) patterns. A prospective cohort of 166 consecutive patients with cardiac arrest in coma was stratified according to four independent EEG patterns (benign; RSE; generalized periodic discharges (GPDs); malignant nonepileptiform) and multimodal prognostic indicators. Primary outcomes were survival and cerebral performance category (CPC) at 6 months. Refractory status epilepticus occurred in 36 patients (21.7%) and was treated with an aggressive standardized protocol as long as multimodal prognostic indicators were not unfavorable. Refractory status epilepticus started after 3 ±â€¯2.3 days after cardiac arrest and lasted 4.7 ±â€¯4.3 days. A benign electroencephalographic patterns was recorded in 76 patients (45.8%), a periodic pattern (GPDs) in 13 patients (7.8%), and a malignant nonepileptiform EEG pattern in 41 patients (24.7%). The four EEG patterns were highly associated with different prognostic indicators (low flow time, clinical motor seizures, N20 responses, neuron-specific enolase (NSE), neuroimaging). Survival and good neurological outcome (CPC 1 or 2) at 6 months were 72.4% and 71.1% for benign EEG pattern, 54.3% and 44.4% for RSE, 15.4% and 0% for GPDs, and 2.4% and 0% for malignant nonepileptiform EEG pattern, respectively. Aggressive and prolonged treatment of RSE may be justified in cardiac arrest patients with favorable multimodal prognostic indicators.

Effectiveness and safety of spinal anesthesia in patients undergoing open radical retropubic prostatectomy.

OBJECTIVE: Prostate cancer is one of the most widespread neoplasms affecting the male gender. The most commonly used procedures in various urological centers are laparoscopic and robotic surgery because they are considered minimally invasive techniques. We present our experience in traditional open radical prostatectomy performed under spinal anesthesia. MATERIALS AND METHODS: We reviewed the clinical courses of 88 consecutive patients who underwent open radical prostatectomy performed under spinal anesthesia at our Institution. RESULTS: Median age: 67.7 years. Median follow up duration: 48 months. Median pre-operative PSA: 15,9 ng/ml, median Prostate weight: 44.5 gr, median surgical time: 96.5 minutes (range 55-138). Perioperative complications were recorded. The most frequent complication was anemia, 9 cases need blood transfusion after surgery. Complications directly related to spinal anesthesia were not observed. Most patients were discharged within 5 days from the procedure. After two weeks we observed a quick recovery of total continence in 90% of patients. After 6 months all patients were perfectly continent. Erectile dysfunction after 6 months was reported by 48 patients. CONCLUSIONS: The reasons why the gold standard of radical prostatectomy surgery has been considered general anesthesia are essentially two: the long duration of the surgical procedure and the associated significant blood loss. Multiple evidences show that radical retropubic prostatectomy can be safely performed under spinal anaesthesia with various advantages. It is therefore no longer justified to consider general anesthesia as the gold standard for radical prostatectomy with an open technique.

Neurologic outcome of postanoxic refractory status epilepticus after aggressive treatment.

OBJECTIVE: To investigate neurologic outcome of patients with cardiac arrest with refractory status epilepticus (RSE) treated with a standardized aggressive protocol with antiepileptic drugs and anesthetics compared to patients with other EEG patterns. METHODS: In the prospective cohort study, 166 consecutive patients with cardiac arrest in coma were stratified according to 4 independent EEG patterns (benign, RSE, generalized periodic discharges [GPDs], malignant nonepileptiform) and multimodal prognostic indicators. Primary outcomes were survival and cerebral performance category (CPC) at 6 months. RESULTS: RSE occurred in 36 patients (21.7%) and was treated with an aggressive standardized protocol as long as multimodal prognostic indicators were not unfavorable. RSE started after 3 ± 2.3 days after cardiac arrest and lasted 4.7 ± 4.3 days. A benign EEG pattern was recorded in 76 patients (45.8%); a periodic pattern (GPDs) was seen in 13 patients (7.8%); and a malignant nonepileptiform EEG pattern was recorded in 41 patients (24.7%). The 4 EEG patterns were highly associated with different prognostic indicators (low-flow time, clinical motor seizures, N20 responses, neuron-specific enolase, neuroimaging). Survival and good neurologic outcome (CPC 1 or 2) at 6 months were 72.4% and 71.1% for benign EEG pattern, 54.3% and 44.4% for RSE, 15.4% and 0% for GPDs, and 2.4% and 0% for malignant nonepileptiform EEG pattern, respectively. CONCLUSIONS: Aggressive and prolonged treatment of RSE may be justified in patients with cardiac arrest with favorable multimodal prognostic indicators.

Effects of extracorporeal cardiopulmonary resuscitation on neurological and cardiac outcome after ischaemic refractory cardiac arrest.

BACKGROUND: Extracorporeal cardiopulmonary resuscitation is increasingly recognised as a rescue therapy for refractory cardiac arrest, nevertheless data are scanty about its effects on neurologic and cardiac outcome. The aim of this study is to compare clinical outcome in patients with cardiac arrest of ischaemic origin (i.e. critical coronary plaque during angiography) and return of spontaneous circulation during conventional cardiopulmonary resuscitation vs refractory cardiac arrest patients needing extracorporeal cardiopulmonary resuscitation. Moreover, we tried to identify predictors of survival after successful cardiopulmonary resuscitation. METHODS: We enrolled 148 patients with ischaemic cardiac arrest admitted to our hospital from 2011-2015. We compared clinical characteristics, cardiac arrest features, neurological and echocardiographic data obtained after return of spontaneous circulation (within 24 h, 15 days and six months). RESULTS: Patients in the extracorporeal cardiopulmonary resuscitation group ( n=63, 43%) were younger (59±9 vs 63±8 year-old, p=0.02) with lower incidence of atherosclerosis risk factors than those with conventional cardiopulmonary resuscitation. In the extracorporeal cardiopulmonary resuscitation group, left ventricular ejection fraction was lower than conventional cardiopulmonary resuscitation at early echocardiography (19±16% vs 37±11 p<0.01). Survivors in both groups showed similar left ventricular ejection fraction 15 days and 4-6 months after cardiac arrest (46±8% vs 49±10, 47±11% vs 45±13%, p not significant for both), despite a major extent and duration of cardiac ischaemia in extracorporeal cardiopulmonary resuscitation patients. At multivariate analysis, the total cardiac arrest time was the only independent predictor of survival. CONCLUSIONS: Extracorporeal cardiopulmonary resuscitation patients are younger and have less comorbidities than conventional cardiopulmonary resuscitation, but they have worse survival and lower early left ventricular ejection fraction. Survivors after extracorporeal cardiopulmonary resuscitation have a neurological outcome and recovery of heart function comparable to subjects with return of spontaneous circulation. Total cardiac arrest time is the only predictor of survival after cardiopulmonary resuscitation in both groups.
