Objective. To compare the efficacy of a local anesthetic cream and music distraction in reducing or preventing pain from needle puncture (intravenous cannulation) in children. A secondary aim was to examine the influence of age on the pain report and behavior and on the therapeutic outcome. Methodology. Children aged 4 to 16 years (N = 180) who were to undergo surgery under general anesthesia via intravenous cannulation were randomly allocated to one of three interventions. The comparison of lidocaine-prilocaine emulsion (EMLA, Astra) and a placebo emulsion was double-blind. Stratification by age group (4 to 6, 7 to 11, 12 to 16) ensured an equal number of children (20) in each intervention/age group category. A global assessment of the behavioral reaction to the procedure was made by the principal investigator, taking into account vocal, verbal, facial, and motor responses. The child was asked to assess pain severity on the Faces Pain Scale (FPS) and a visual analogue toy (VAT). The scales were applied conservatively as ordinal scales: FPS 0 to 6; VAT 0 to 10. Results. Children who received lidocaine-prilocaine emulsion reported less pain (mean FF5 score = 1.42) compared with placebo emulsion (mean FPS score = 2.58) and with music distraction (mean FPS = 2.62). There was a highly significant therapeutic effect (P < .001) on the self-report and behavioral scores. Younger children, regardless of intervention, reported significantly more pain than the older children (mean FPS scores: 2.85, 2.33, 1.43 for age groups 4 to 6, 7 to 11, and 12 to 16 respectively; P < .001). The superiority of the local anesthetic emulsion was maximal in the youngest age group (4 to 6) almost eliminating pain-related behavior, and multiple regression analysis confirmed significant age and treatment effects and revealed interaction between therapeutic effect and age. Although a trend favoring the active emulsion was evident in the older children (7 to 11, 12 to 16) the differences were not significant. The pain scores were influenced by the type (gauge) of cannula, but this did not affect the conclusion regarding therapeutic and age effects. There was no influence of sex, experience with venipuncture, or whether the child was anxious on arrival in the operating room. Conclusions. The results show that lidocaine-prilocaine emulsion is highly effective in preventing pain from venipunctures in young children the group in most need of prevention.
SummaryObjective: The aim of this study was to evaluate pre-, intra-, and postoperative anesthetic parameters in endoscopic strip craniectomy in order to improve anesthesiological care. Materials and Methods:This is a retrospective patient cohort study of our first 121 patients treated by endoscopic strip craniectomy. Preoperative as well as intra-and postoperative anesthesiological and neurological parameters were analyzed. Furthermore, the need for intensive care unit admission, blood loss, and blood transfusion rate were measured. Results:The mean age of patients was 3.9 months (standard deviation = 1) at a mean weight of 6.3 kg (standard deviation = 1.3). Comorbidity was registered in 13 (11%) patients of which 5 had syndrome-related comorbidities. Mean duration of anesthesia was 131 minutes (standard deviation = 32) . One hundred and sixteen patients were induced by mask induction with sevoflurane and 5 patients were induced intravenously.In 10 patients, mild intraoperative hypothermia (between 35 and 36 degrees Celsius) occurred. The mean estimated blood loss was 35.4 mL (standard deviation = 28.9) and blood transfusion rate was 21.5%. Brief and small intraoperative oxygen saturation drops were common during this study. No indication for venous air embolism was found based on endtidal CO 2 . Postoperative temperature above 38 degrees Celsius occurred 16 times and benign deviations in postoperative cardiopulmonary parameters occurred in 17 patients. Postoperative pain management was mainly established by paracetamol and low-dose morphine when necessary. No postoperative neurological symptoms were reported and no deaths occurred. Conclusion:These patients had a relatively short intraoperative course with stable vital parameters during surgery. We report a low incidence of significant venous air embolism, a blood transfusion rate of 21% and only minor perioperative disturbances in vital parameters.
Background The need for external cerebrospinal fluid (CSF) drains in aneurysmal subarachnoid haemorrhage (aSAH) patients is common and might lead to additional complications. Objective A relation between the presence of an external CSF drain and complication risk is investigated. Methods A prospective complication registry was analysed retrospectively. We included all adult aSAH patients admitted to our academic hospital between January 2016 and January 2018, treated with an external CSF drain. Demographic data, type of external drain used, the severity of the aSAH and complications, up to 30 days after drain placement, were registered. Complications were divided into (1) complications with a direct relation to the external CSF drain and (2) complications that could not be directly related to the use of an external CSF drain referred to as medical complications Results One hundred and forty drains were implanted in 100 aSAH patients. In total, 112 complications occurred in 59 patients. Thirty-six complications were drain related and 76 were medical complications. The most common complication was infection (n = 34). Drain dislodgement occurred 16 times, followed by meningitis (n = 11) and occlusion (n = 9). A Poisson model showed that the mean number of complications raised by 2.9% for each additional day of drainage (95% CI: 0.6–5.3% p = 0.01). Conclusion Complications are common in patients with aneurysmal subarachnoid haemorrhage of which 32% are drain-related. A correlation is present between drainage period and the number of complications. Therefore, reducing drainage period could be a target for further improvement of care.
Our think tank tasked by the Dutch Health Council, consisting of Radboud University Nijmegen Honours Academy students with various backgrounds, investigated the implications of Deep Brain Stimulation (DBS) for psychiatric patients. During this investigation, a number of methodological, ethical and societal difficulties were identified. We consider these difficulties to be a reflection of a still fragmented field of research that can be overcome with improved organization and communication. To this effect, we suggest that it would be useful to found a centralized DBS organization. Such an organization makes it possible to 1) set up and maintain a repository, 2) facilitate DBS studies with a larger sample size, 3) improve communication amongst researchers, clinicians and ethical committees, and 4) improve communication between DBS experts and the public at large.
