RESUMEN

OBJECTIVE: Over the past decade, the Enhanced Recovery After Surgery (ERAS) program has demonstrated its effectiveness and efficiency in improving postoperative care and enhancing recovery across various surgical fields. Preliminary results of ERAS protocol implementation in craniosynostosis surgery are presented. METHODS: An ERAS protocol was developed and implemented for cranial pediatric neurosurgery, focusing on craniosynostosis repair. The study incorporated a pre-ERAS group consisting of a consecutive series of patients who underwent craniosynostosis repair surgery prior to the implementation of the ERAS protocol; the results were compared with a consecutive group of patients who had been prospectively collected since the introduction of the ERAS for craniosynostosis protocol. The safety, feasibility, and efficiency of the ERAS protocol in pediatric neurosurgery was evaluated, through the collection of clinical data from the pre-, intra-, and postoperative phase. Surgery-related complications were evaluated according to the Clavien-Dindo classification. Costs of the stays were obtained using a microcosting approach. RESULTS: A total of 35 pre-ERAS patients and 10 ERAS patients were included. Scaphocephaly was the most common pathology in both groups. The overall compliance with the pre-, intra-, and postoperative criteria significantly increased-from 35.5%, 64.4%, and 54.7%, respectively, in each phase to 94%, 90%, and 84% (p < 0.001). The authors noticed a reduction in the average opioid dose used per patient in the ERAS group (p = 0.004), and they observed a trend toward a decreased mean length of stay from 5.2 days in the pre-ERAS group to 4.6 days in the ERAS group, without an increase of the rate of readmission within 30 days of surgery. The rate of complications decreased but this difference was not statistically significant. The hospital costs lowered significantly: from 21,958 Confederatio Helvetica Francs (CHF) in the pre-ERAS group to 18,936 CHF in the ERAS group (p = 0.02). CONCLUSIONS: The ERAS protocol represents a safe and cost-effective tool for the perioperative management of craniosynostosis. It showed its positive impact on the analgesia provided and on the reduction of in-hospital costs for these patients. ERAS protocols may thus be interesting options in the pediatric neurosurgical field.

RESUMEN

BACKGROUND: Over the past decade, Enhanced Recovery After Surgery (ERAS®) guidelines have been proven to simplify postoperative care and improve recovery in several surgical disciplines. The authors set out to create and launch an ERAS® program for cranial neurosurgery that meets official ERAS® Society standards. The authors summarize the successive steps taken to achieve this goal in two specific neurosurgical conditions and describe the challenges they faced. METHODS: Pituitary neuroendocrine tumors (Pit-NET) resected by a transsphenoidal approach and craniosynostosis (Cs) repair were selected as appropriate targets for the implementation of ERAS® program in the Department of Neurosurgery. A multidisciplinary team with experience in managing these pathologies was created. A specialized ERAS® nurse coordinator was hired. An ERAS® certification process was performed involving 4 seminars separated by 3 active phases under the supervision of an ERAS® coach. RESULTS: The ERAS® Pit-NET team included 8 active members. The ERAS® Cs team included 12 active members. Through the ERAS® certification process, areas for improvement were identified, local protocols were written, and the ERAS® program was implemented. Patient-centered strategies were developed to increase compliance with the ERAS® protocols. A prospective database was designed for ongoing program evaluation. Certification was achieved in 18 months. Direct costs and time requirements are reported. CONCLUSION: Successful ERAS® certification requires a committed multidisciplinary team, an ERAS® coach, and a dedicated nurse coordinator.

RESUMEN

: Viscoelastic tests and impedance aggregometry allow coagulation evaluation at the bedside, but reference values are scarce in pediatrics. The aim of this study was to establish reference values of thromboelastometry and impedance aggregometry for this population and compare it between age groups. This prospective, single-center, observational study evaluates viscoelastic tests and impedance aggregometry in children with congenital heart disease. A total of 204 children were included with a median age of 3.6 years old. We provide references values for this population with median, percentile 2.5 and percentile 97.5. Infants demonstrate for extrinsic activity a shorter coagulation time (52 [49-55] vs. 56 [51-62] s, P = 0.007) and clot formation time (90 [71-118] vs. 113 [93-146] s, P < 0.0001) so as for intrinsic activity a shorter clot formation time (53 [44-69] vs. 75 [59-92] s, P < 0.0001). The maximal clot firmness was significantly stronger in infants for extrinsic (65 [61-69] vs. 59 [54-63] mm, P < 0.0001), intrinsic (68 [64-70] vs. 61 [57-65] mm, P < 0.0001), and fibrinogen (12 [9-16] vs. 10 [8-13] mm, P = 0.02) activities. Platelet aggregation was significantly higher in infants with an amplitude at 6 min of 28 [23-34] vs. 22 [15-27] Ω, P less than 0.0001, a maximum speed of 11 [9-13] vs. 7 [5-10] Ω/min, P less than 0.0001, and an area under the curve of 120 [92-135] vs. 86 [59-112] Ω min, P less than 0.0001. We provided the first reference values for impedance aggregometry and thromboelastometry in children with congenital heart disease. We showed that these infants tend to have accelerated coagulation and stronger clot firmness compared with older children, but this finding may have only minimal relevance when treating a bleeding child. Trial registration number: ClinicalTrials.gov (clinicaltrials.gov/ct2/show/NCT02387944).

RESUMEN

We present 2 infants with the rare association of long congenital tracheal stenosis, ventricular septal defect, and pulmonary hypertension. We describe a step-by-step assessment of the patients and the necessary procedures for a successful concomitant repair of both cardiac and tracheal malformations. The use of a helium-oxygen mixture (heliox) for the induction of anesthesia and pre-cardiopulmonary bypass is discussed.

RESUMEN

OBJECTIVE: An important aspect of perioperative care in pediatric cardiac surgery is maintenance of optimal hemodynamic status using vasoactive/inotropic agents. Conventionally, this has focused on maintenance of cardiac output rather than perfusion pressure. However, this approach has been abandoned in our center in favor of one focusing primarily on perfusion pressure, which is presented here and compared to the conventional approach. DESIGN: A retrospective study. SETTING: Regional center for congenital heart disease. University Hospital of Lausanne, Switzerland. PATIENTS: All patients with Aristotle risk score ≥8 that underwent surgery from 1996 to 2012 were included. Patients operated between 1996 and 2005 (Group 1: 206 patients) were treated according to the conventional approach. Patients operated between 2006 and 2012 (Group 2: 217 patients) were treated according to our new approach. INTERVENTIONS: All patients had undergone surgery for correction or palliation of congenital cardiac defects. OUTCOME MEASUREMENTS: Mortality, duration of ventilation and inotropic treatment, use of ECMO, and complications of poor peripheral perfusion (need for hemofiltration, laparotomy for enterocolitis, amputation). RESULTS: The two groups were similar in age and complexity. Mortality was lower in group 2 (7.3% in group 1 vs 1.4% in group 2, P < .005). Ventilation times (hours) and number of days on inotropic/vasoactive treatment (all agents), expressed as median and interquartile range [Q1-Q3] were shorter in group 2: 69 [24-163] hours in group 1 vs 35 [22-120] hours in group 2 (P < .01) for ventilation, and 9 [3-5] days in group 1 vs 7 [2-5] days in group 2 (P < .05) for inotropic/vasoactive agents. There were no differences in ECMO usage or complications of peripheral perfusion. CONCLUSIONS: Results in pediatric cardiac surgery may be improved by shifting the primary focus of perioperative care from cardiac output to perfusion pressure.

RESUMEN

We report successful use of levosimendan after failed balloon angioplasty in a critically ill neonate with coarctation of aorta (CoA) and severe low cardiac output syndrome (LCOS). Treatment with levosimendan improved left heart function, and decreased lactate and brain natriuretic peptide levels. To our knowledge, this is the first report on the safe and successful use of levosimendan in the management of LCOS due to severe CoA in a neonate awaiting surgical repair.

RESUMEN

The evidence for endothelial dysfunction in sepsis is mostly restricted to animal models. We investigated endothelial function in the skin microcirculation of eight patients hospitalized for septic shock in an intensive care unit (ICU). All patients required adrenergic support. Twelve hemodynamically stable ICU patients without sepsis who did not receive any vasoactive medication were used as controls. The two groups were of similar age and sex ratio. For additional reference, 16 healthy, nonsmoking subjects matched for age and sex to the first two groups were also studied. The evaluation of endothelial function was based on the comparison of skin blood flow responses to iontophoretically applied acetylcholine (Ach, an endothelium-dependent vasodilator) and sodium nitroprusside (SNP, an endothelium-independent vasodilator). Skin blood flow was measured on the volar face of the forearm using laser Doppler imaging. Before application of Ach or SNP, the mean baseline skin blood flow was below 100 perfusion units (PU) in all subjects and did not differ between groups. The maximal increase in blood flow elicited by both agents was significantly depressed in the patients with sepsis (Ach: 167 +/- 63 PU; SNP: 138 +/- 34 PU, mean +/- SD) compared with the ICU control patients (Ach: 291 +/- 135 PU, P < 0.05; SNP: 261 +/- 121 PU, P < 0.01) and the healthy, nonsmoking groups (Ach: 336 +/- 98 PU, P < 0.01; SNP: 304 +/- 81 PU, P < 0.01). The ratio of responses to Ach and SNP did not significantly differ between groups (septic: 1.22 +/- 0.40; ICU control 1.18 +/- 0.46, healthy, nonsmoking 1.12 +/- 0.24, P = 0.86). Thus, sepsis was not associated with a selective depression of the endothelium-dependent response. These results suggest that the capacity of the endothelium to produce signals for vasorelaxation remains intact in the skin microcirculation of patients with septic shock.

RESUMEN

Endurance training modifies the thermoregulatory control of skin blood flow, as manifested by a greater augmentation of skin perfusion for the same increase in core temperature in athletes, in comparison with sedentary subjects. In this study, we tested the hypothesis that a component of this adaptation might reside in a higher ability of cutaneous blood vessels to respond to vasodilatory stimuli. We recruited healthy nonsmoking males, either endurance trained or sedentary, in two different age ranges (18-35 y and >50 y). Skin blood flow was measured in the forearm skin, using a laser Doppler imager, allowing to record the vasodilatory responses to the following stimuli: iontophoresis of acetylcholine (an endothelium-dependent vasodilator), iontophoresis of sodium nitroprusside (a nitric oxide donor), and release of a temporary interruption of arterial inflow (reactive hyperemia). There was no effect of training on reactive hyperemia or the response to acetylcholine. In contrast, the increase in perfusion following the iontophoresis of sodium nitroprusside, expressed in perfusion units, was larger in trained than in sedentary subjects (younger: 398 +/- 54 vs 350 +/- 87, p < 0.05; older 339 +/- 72 vs 307 +/- 66, p < 0.05). In conclusion, endurance training enhances the vasodilatory effects of nitric oxide in the human dermal microcirculation, at least in forearm skin. These observations have considerable physiologic interest in view of recent data indicating that nitric oxide mediates in part the cutaneous vasodilation induced by heat stress in humans. Therefore, the augmentation of nitric oxide bioactivity in the dermal microcirculation might be one mechanism whereby endurance training modifies the thermoregulatory control of skin blood flow.
