Validation francophone de la grille d’évaluation de la douleur-déficience intellectuelle – version postopératoire

Purpose

The aim of the study was to test the validity of a French language version of the Non-Communicating Children’s Pain Checklist - Postoperative Version (NCCPC-PV): grille d’évaluation de la douleur-déficience intellectuelle (GED-DI).

Methods

We assessed the intensity of pain in 87 intellectually disabled surgical patients recruited in four Canadian and French hospitals in the pre- and post-operative settings using the GED-DI, a 100-mm visual analogue pain scale (VAS) and the Rosen sedation scale. The validity of the GED-DI was measured by the difference in scores between pre- and postoperative conditions. The checklist was made up of 30 items divided into seven subgroups. Items were rated from 0 to 3 for a total score ranging from 0 to 90 points.

Results

The mean (standard deviation) age of the patients was 17 (11) yr and the mean mental age 24.5 (24) months. The total GED-DI score was 6.1 (4.9) pre- and 13.4 (11.2) post-surgery (P < 0.001). All subgroups had a higher score after surgery (P < 0.001). The receiver operating characteristic (ROC) curves, comparing the absence of pain to mild pain scores and moderate to severe pain scores, showed a cutoff at 6 (mild pain) and 11 (moderate to severe pain).

Conclusion

The French version of the NCCPC-PV can be used to assess pain in non-communicating patients with intellectual disabilities in a postoperative setting. It has good content validity, as the total pre-surgery score for the GED-DI was significantly lower than the postoperative score, and showed a good concurrent validity when compared to the VAS.     

Techniques de mesure de la pression intracrânienne

A wide variety of monitoring devices have been used for intracranial pressure measurement. The aim of this article is to present the most common devices and to assess their accuracy, stability and complications, with reference to current literature. Measurement with an intraventricular catheter remains the reference method. However new techniques with distal measurement (fiberoptic or strain gauge) seem to be accurate, but have a higher cost. Some practical problems, such as the zero pressure reference level and the side of measurement, are also discussed.

Modification du réflexe de déglutition au cours de la période périopératoire

The swallowing reflex is one of the major mechanisms protecting the lungs against aspiration of foreign material. Its complex time course requires a perfect coordination with ventilation, as the aerodigestive crossroads are common for both functions. Physiological factors as ageing, as well as mechanical and pharmacological agents, may contribute to swallowing reflex alterations. Moreover, endotracheal intubation and most anaesthetic agents may impair the swallowing function and favour the occurrence of aspiration. This review discusses the normal swallowing process and its alterations by agents currently used in anaesthesia. Furthermore, the effect of intubation as well as changes related to co-existing diseases are considered.     

Complications rénales au décours de la greffe de cellules souches hématopoïétiques

Hematopoietic stem cell transplantation is a widely used therapeutic modality for many, mainly malignant, diseases. Toxicities of this procedure include acute and chronic renal dysfunction. Acute renal failure, generally reversible is due to acute tubular necrosis (tumor lysis syndrome, marrow-infusion toxicity, sepsis, nephrotoxins), hepatic veno-occlusive disease or acute graft-versus-host disease. Chronic renal failure is often multifactorial, caused by conditioning-associated endothelial cell toxicity (bone marrow transplant nephropathy) and calcineurin inhibitors toxicity. Renal pathologic findings are somewhat similar to thrombotic microangiopathy, with sometimes systemic disease. Rare cases of nephrotic syndrome have been described after hematopoietic stem cell transplantation, mainly membranous nephropathy, associated with graft-versus-host disease. Therapeutic options for renal dysfunction after hematopoietic stem cell transplantation are limited but kidney transplantation is possible in case of end-stage renal disease.     

Place de la laminoplastie dans le traitement de la myélopathie cervicale d’origine arthrosique

Cervical spondylotic myelopathy (CSM) is a common condition. Uninstrumented laminectomy may be complicated by postoperative instability, whereas anterior or posterior decompression with fusion may be associated with stiffness and adjacent segment disease. Cervical laminoplasty, initially oriented towards pediatric patients and ossification of the posterior longitudinal ligament, becomes an interesting surgical alternative to decompress and reconstruct cervical anatomy without fusion. Eighteen patients (12 men, 6 women), mean age 64.2 who presented with CSM were treated surgically using multilevel laminoplasty, and reviewed after 1 month, 6 months, 1 year and 2 years. Clinical evaluation was performed based on the Benzel-JOA and Nurick scores. The preoperative mean Benzel-JOA score was 13.55; Preoperative mean Nurick score was 1.88. Preoperative MRI was carried-out in 16/18 patients. Intramedullary hyperintensity in T2 was observed in 6 patients. The operation was performed on 2 levels (4 patients) 3 levels (11 patients) and 4 levels (3 patients). We used the open-door hinged laminoplasty technique, using metallic implants, without bone graft. At one month FU, mean JOA score was 15.44, and Nurick dropped to 1.05. At 6 months, mean JOA was 16.28 and Nurick was 0.71. At one year, the mean JOA score was 16.16, and Nurick was 0.83. At 2 years, mean JOA was 17.5, and Nurick was 0.25. One infection, one dural tear and one transient episode of C5 paresthesia were observed. We conclude that spinal cord decompression by open-door laminoplasty for CSM allows significant clinical improvement observed progressively in the two years following surgery.
