Preoperative risk factors for intra-operative bleeding in pediatric liver transplantation.

Pediatr Transplant 2016 Dec 29;20(8):1065-1071. Epub 2016 Sep 29.

Pediatric surgery unit, Hôpital Necker enfants malades, Paris, France.

This study analyzes the preoperative risk factors for intra-operative bleeding in our recent series of pediatric LTs. Between November 2009 and November 2014, 84 consecutive isolated pediatric LTs were performed in 81 children. Potential preoperative predictive factors for bleeding, amount of intra-operative transfusions, postoperative course, and outcome were recorded. Cutoff point for intra-operative HBL was defined as intra-operative RBC transfusions ≥1 TBV. Twenty-six patients (31%) had intra-operative HBL. One-year patient survival after LT was 66.7% (CI 95%=[50.2-88.5]) in HBL patients and 83.8% (CI 95%=[74.6-94.1]) in the others (P=.054). Among 13 potential preoperative risk factors, three of them were identified as independent predictors of high intra-operative bleeding: abdominal surgical procedure(s) prior to LT, factor V level ≤30% before transplantation, and ex situ parenchymal transsection of the liver graft. Based on these findings, we propose a simple score to predict the individual hemorrhagic risk related to each patient and graft association. This score may help to better anticipate intra-operative bleeding and improve patient's management.

Critical incidents in a French department of paediatric anaesthesia.

Anaesth Crit Care Pain Med 2017 Apr 30;36(2):103-107. Epub 2016 Jul 30.

Department of Anaesthesiology and Critical Care Medicine, Hôpital Universitaire Necker-Enfants-Malades, AP-HP, University Paris Descartes, 149, rue de Sèvres, 75743 Paris, France. Electronic address:

Background: Several studies have highlighted the importance of critical incident (CI) reporting in order to enhance patient safety. We have implemented an anonymous procedure for CI reporting in our department of paediatric anaesthesia. This study aims at analysing those CIs so as to improve patient care and risk management.

Material And Methods: CIs were reported by the anaesthetic team using the World Health Organization classification and analysed using the ORION methodology. CIs were classified according to type, surgery and complications. Risk factors and consequences for patients and for the institution were analysed. Risk factors with high degree of harm for the patient were identified using a univariate analysis and odds ratios (OR).

Results: Over an 18-month period, 114 CIs were reported for 103 patients (median age: 7.0 years [95% CI: 3.6-9.8]). We found that 29.9% of reported CIs had consequences for the patients and 76.3% were considered preventable. The two main types of CI were "respiratory" (28.8%) and "drug-related" (22.8%) incidents. The main risk factor was 'human error' (42.3%). Several consequences for the patient and the hospital were identified. An ASA score≥3 (OR: 2.52; [95% CI: 1.10-5.78]) was an independent risk factor for a high degree of patient harm.

Conclusion: Improving quality of care must be a priority for paediatric anaesthesiologists as most of the CIs observed are preventable and have consequences for the patient and the institution.

Trans-facet-joint approach to pulsed radiofrequency ablation of the L5 dorsal root ganglion in a patient with degenerative spondylosis and scoliosis.

Pain Pract 2008 May-Jun;8(3):202-5

Unit Pain, Hospital Universitario Puerta de Hierro, Madrid, Spain.

Mechanical low back pain secondary to degenerative facet joint changes is a common reason for referral to pain clinics. When these changes cause encroachment into the intervertebral foramen, radicular pain may result. While pulsed radiofrequency of the dorsal root ganglion can be used in this setting, the anatomic deformity may make the transforaminal approach difficult. We report a case where a trans-facet approach was used successfully and describe the technique.
