RESUMEN
BACKGROUND: It is well established that the use of a postoperative drain after chronic subdural hematoma surgery reduces recurrence rates, and it is common to use a postoperative drain for longer than 24 h. It is unclear whether this is superior to a shorter drainage time of less than 24 h. Our aim was to compare a postoperative drainage longer or shorter than 24 h after chronic subdural hematoma evacuation. MATERIALS AND METHODS: In this retrospective single centre study, 207 adult patients undergoing chronic subdural hematoma evacuation with a postoperative drainage longer (LDT-group) or shorter (SDT-group) than 24 h were compared regarding recurrence, mortality within 6 months and complications requiring hospital admission within 30 days. Length of hospital stay was also recorded. An active subgaleal drain was used. In addition to the retrospective cohort, we also studied the total volume drained per hour after cSDH surgery in a prospective cohort of 10 patients. RESULTS: Recurrence occurred in 12/96 (12.5%) in the LDT-group and in 13/111 (11.7%) patients in the SDT-group (p = 0.15). There was no significant difference between groups regarding recurrence, complications or mortality. The prospective cohort showed that most of the drainage occurred within the first hours after surgery. CONCLUSION: Our data show that a postoperative drainage duration of less than 24 h does not lead to an increase in recurrence, complications or mortality compared to a drainage time of more than 24 h. A shorter drainage duration (< 24 h) after cSDH surgery facilitated earlier mobilisation and shorter hospital stay.

BACKGROUND: Chronic subdural hematomas (cSDH) are one of the most common conditions requiring neurosurgical treatment. The reported recurrence after surgery is 3-21.5% with closed system drainage. In clinical practice, irrigation fluids at body temperature (37 °C) and at room temperature (22 °C) are routinely used in the evacuation of cSDH. Our hypothesis was that irrigation at body temperature might have more beneficial effects on coagulation and solubility of the chronic subdural hematoma than irrigation at room temperature. The aim of this study was to compare the effects of different intraoperative irrigation fluid temperatures on recurrence rates. METHODS: This was a retrospective study where we included all consecutive patients from a defined geographical area of western Sweden between September 2013 and November 2014. In the course of 6 months, we performed intraoperative irrigation at body temperature (37 °C, BT-group) during burr hole evacuation of chronic subdural hematoma. This was then compared with the previous 6-month period, when irrigation fluid at room temperature (22 °C, RT-group) was used. The primary endpoint was same-sided recurrence in need of reoperation within 6 months. RESULTS: Recurrence occurred in 11 of 84 (13.1%) patients in the RT-group compared with 4 of 88 (4.5%) in the BT-group (p = 0.013). There were no significant between-group differences regarding age, sex, duration of surgery, frequency of bilateral hematomas, hematoma density, and use of anticoagulant/antithrombotic therapy. CONCLUSION: Our study demonstrates that intraoperative irrigation fluid at body temperature is associated with lower recurrence rates compared with irrigation fluid at room temperature. To investigate this further, a prospective randomized controlled trial has been initiated (clinicaltrials.gov, NCT0275235). TRIAL REGISTRATION: ClinicalTrials.gov Identifier: NCT0275235.

BACKGROUND: Supratentorial intracerebral haemorrhage (ICH) carries an excessive mortality and morbidity. Although surgical ICH treatment can be life-saving, the indications for surgery in larger cohorts of ICH patients are controversial and not well defined. We hypothesised that surgical indications vary substantially among neurosurgical centres in Sweden. OBJECTIVE: In this nation-wide retrospective observational study, differences in treatment strategies among all neurosurgical departments in Sweden were evaluated. METHODS: Patient records, neuroimaging and clinical outcome focused on 30-day mortality were collected on each operated ICH patient treated at any of the six neurosurgical centres in Sweden from 1 January 2011 to 31 December 2015. RESULTS: In total, 578 consecutive surgically treated ICH patients were evaluated. There was a similar incidence of surgical treatment among different neurosurgical catchment areas. Patient selection for surgery was similar among the centres in terms of patient age, pre-operative level of consciousness and co-morbidities, but differed in ICH volume, proportion of deep-seated vs. lobar ICH and pre-operative signs of herniation (p < .05). Post-operative patient management strategies, including the use of ICP-monitoring, CSF-drainage and mechanical ventilation, varied among centres (p < .05). The 30-day mortality ranged between 10 and 28%. CONCLUSIONS: Although indications for surgical treatment of ICH in the six Swedish neurosurgical centres were homogenous with regard to age and pre-operative level of consciousness, important differences in ICH volume, proportion of deep-seated haemorrhages and pre-operative signs of herniation were observed, and there was a substantial variability in post-operative management. The present results reflect the need for refined evidence-based guidelines for surgical management of ICH.

BACKGROUND: Patients with subarachnoid haemorrhage (SAH) frequently develop cardiac complications in the acute phase after the bleeding. Although a number of studies have shown that increased levels of cardiac biomarkers after SAH are associated with a worse short-term prognosis, no prospective, consecutive study has assessed the association between biomarker release and long-term outcome. We aimed to evaluate whether the cardiac biomarkers, high-sensitive troponin T (hsTnT) and N-terminal pro B-type natriuretic peptide (NTproBNP), were associated with poor 1-year neurological outcome and cerebral infarction due to delayed cerebral ischaemia (CI-DCI). METHODS: In this single-centre prospective observational study, all consecutive patients admitted to our neurointensive care unit from January 2012 to December 2013 with suspected/verified SAH with an onset of symptoms <72 hours were enrolled. Blood samples for hsTnT and NTproBNP were collected during three consecutive days following admission. Patients were followed-up after 1 year using the Glasgow Outcome Scale Extended (GOSE). Poor neurological outcome was defined as GOSE ≤ 4. RESULTS: One hundred and seventy seven patients with suspected SAH were admitted during the study period; 143 fulfilled inclusion criteria and 126 fulfilled follow-up. Forty-one patients had poor 1-year outcome and 18 had CI-DCI. Levels of hsTnT and NTproBNP were higher in patients with poor outcome and CI-DCI. In multivariable logistic regression modelling age, poor neurological admission status, cerebral infarction of any cause and peak hsTnT were independently associated with poor late outcome. Both peak hsTnT and peak NTproBNP were independently associated with CI-DCI. CONCLUSION: Increased serum levels of the myocardial damage biomarker hsTnT, when measured early after onset of SAH, are independently associated with poor 1-year outcome. Furthermore, release of both hsTnT and NTproBNP are independently associated with CI-DCI. These findings render further support to the notion that troponin release after SAH is an ominous finding. Future studies should evaluate whether there is a causal relationship between early release of biomarkers of myocardial injury after SAH and neurological sequelae.

Importance: The effect of a physical property of irrigation fluid (at body vs room temperature) on recurrence rate in the evacuation of chronic subdural hematoma (cSDH) needs further study. Objective: To explore whether irrigation fluid temperature has an influence on cSDH recurrence. Design, Setting, and Participants: This was a multicenter randomized clinical trial performed between March 16, 2016, and May 30, 2020. The follow-up period was 6 months. The study was conducted at 3 neurosurgical departments in Sweden. All patients older than 18 years undergoing cSDH evacuation during the study period were screened for eligibility in the study. Interventions: The study participants were randomly assigned by 1:1 block randomization to the cSDH evacuation procedure with irrigation fluid at room temperature (RT group) or at body temperature (BT group). Main Outcomes and Measures: The primary end point was recurrence requiring reoperation within 6 months. Secondary end points were mortality, health-related quality of life, and complication frequency. Results: At 6 months after surgery, 541 patients (mean [SD] age, 75.8 [9.8] years; 395 men [73%]) had a complete follow-up according to protocol. There were 39 of 277 recurrences (14%) requiring reoperation in the RT group, compared with 16 of 264 recurrences (6%) in the BT group (odds ratio, 2.56; 95% CI, 1.38-4.66; P < .001). There were no significant differences in mortality, health-related quality of life, or complication frequency. Conclusions and Relevance: In this study, irrigation at body temperature was superior to irrigation at room temperature in terms of fewer recurrences. This is a simple, safe, and readily available technique to optimize outcome in patients with cSDH. When irrigation is used in cSDH surgery, irrigation fluid at body temperature should be considered standard of care. Trial Registration: ClincalTrials.gov Identifier: NCT02757235.

OBJECTIVE: To investigate long-term survival, neurologic outcome, and quality of life in patients with spontaneous supratentorial intracerebral hemorrhage (ICH) treated with craniotomy and hematoma evacuation. METHODS: A nationwide multicenter retrospective analysis of 341 patients who underwent craniotomy and evacuation of supratentorial ICH between January 1, 2011, and December 31, 2015, was performed. Baseline characteristics associated with 6-month mortality and long-term mortality were investigated. Survivors received a questionnaire about their state of health from which EuroQol 5D (EQ-5D) and modified Rankin scale (mRS) were obtained. Predictors of mortality, unfavorable outcome, and life quality were analyzed. RESULTS: The mean follow-up time was 55.2 months. Predictors of 6-month mortality in multiple regression analysis were age ≥75 years, previous myocardial infarction, lower level of consciousness, and mechanical ventilation. Predictors of long-term mortality were higher age and mechanical ventilation. At follow-up, 49.5% of survivors had a favorable neurologic outcome (mRS ≤3). Predictors of an unfavorable functional outcome were higher age and ICH volume ≥50 mL. The mean EQ-5D health index was 0.719, and the mean EQ-5D visual analog scale score was 53.9. In multiple regression, only a higher mRS score was significantly associated with worse life quality. CONCLUSIONS: Knowledge about survival, functional outcome, and life quality as well as their predictors in this specific patient group is previously primarily described in short-term follow-up. This multicenter study provides novel information in the long-term perspective, which is important for improved surgical decision-making and prognostication.

OBJECTIVE: The authors aimed to develop the first clinical grading scale for patients with surgically treated spontaneous supratentorial intracerebral hemorrhage (ICH). METHODS: A nationwide multicenter study including 401 ICH patients surgically treated by craniotomy and evacuation of a spontaneous supratentorial ICH was conducted between January 1, 2011, and December 31, 2015. All neurosurgical centers in Sweden were included. All medical records and neuroimaging studies were retrospectively reviewed. Independent predictors of 30-day mortality were identified by logistic regression. A risk stratification scale (the Surgical Swedish ICH [SwICH] Score) was developed using weighting of independent predictors based on strength of association. RESULTS: Factors independently associated with 30-day mortality were Glasgow Coma Scale (GCS) score (p = 0.00015), ICH volume ≥ 50 mL (p = 0.031), patient age ≥ 75 years (p = 0.0056), prior myocardial infarction (MI) (p = 0.00081), and type 2 diabetes (p = 0.0093). The Surgical SwICH Score was the sum of individual points assigned as follows: GCS score 15-13 (0 points), 12-5 (1 point), 4-3 (2 points); age ≥ 75 years (1 point); ICH volume ≥ 50 mL (1 point); type 2 diabetes (1 point); prior MI (1 point). Each increase in the Surgical SwICH Score was associated with a progressively increased 30-day mortality (p = 0.0002). No patient with a Surgical SwICH Score of 0 died, whereas the 30-day mortality rates for patients with Surgical SwICH Scores of 1, 2, 3, and 4 were 5%, 12%, 31%, and 58%, respectively. CONCLUSIONS: The Surgical SwICH Score is a predictor of 30-day mortality in patients treated surgically for spontaneous supratentorial ICH. External validation is needed to assess the predictive value as well as the generalizability of the Surgical SwICH Score.
RESUMEN
BACKGROUND: Chronic subdural hematoma (cSDH) is one of the most common conditions encountered in neurosurgical practice. Recurrence, observed in 5-30% of patients, is a major clinical problem. The temperature of the irrigation fluid used during evacuation of the hematoma might theoretically influence recurrence rates since irrigation fluid at body temperature (37 oC) may beneficially influence coagulation and cSDH solubility when compared to irrigation fluid at room temperature. Should no difference in recurrence rates be observed when comparing irrigation-fluid temperatures, there is no need for warmed fluids during surgery. Our main aim is to investigate the effect of irrigation-fluid temperature on recurrence rates and clinical outcomes after cSDH evacuation using a multicenter randomized controlled trial design. METHODS: The study will be conducted in three neurosurgical departments with population-based catchment areas using a similar surgical strategy. In total, 600 patients fulfilling the inclusion criteria will randomly be assigned to either intraoperative irrigation with fluid at body temperature or room temperature. The power calculation is based on a retrospective study performed at our department showing a recurrence rate of 5% versus 12% when comparing irrigation fluid at body temperature versus fluid at room temperature (unpublished data). The primary endpoint is recurrence rate of cSDH analyzed at 6 months post treatment. Secondary endpoints are mortality rate, complications and health-related quality of life. DISCUSSION: Irrigation-fluid temperature might influence recurrence rates in the evacuation of chronic subdural hematomas. We present a study protocol for a multicenter randomized controlled trial investigating our hypothesis that irrigation fluid at body temperature is superior to room temperature in reducing recurrence rates following evacuation of cSDH.
