Le rôle des représentations de la maladie et de la douleur dans la relation patient-thérapeute

Résumé  La rencontre entre patient et thérapeute dans la relation de soins met en présence non seulement deux individus, mais aussi deux systèmes de pensée. Elle suppose donc l'articulation de deux types de savoirs, profane d'une part et scientifique d'autre part. La clarification et la prise en compte des représentations du patient à propos de l'atteinte dont il souffre constitue un enjeu important de la relation. Il en va de même des attentes du thérapeute par rapport à ce qu'il considère comme un comportement douloureux adéquat, par exemple. Faute de la prise en compte des modèles de référence explicites et implicites tant du patient que du thérapeute, la relation peut déboucher sur des malentendus, des réactions d'agressivité, d'anxiété, et conduire à une rupture de cette relation.

Summary  The patient-therapist relationship involves not only two individuals, but also two systems of thinking. It calls forth lay knowledge on the one hand and scientific knowledge on the other hand. The patient's representations about his pain and suffering may play an important role in the patient-health care provider relationship and thus need to be clarified and taken into account. This need also holds true where the therapist's expectations are concerned, for example with regard to what is considered as an adequate pain behavior. Failing to take into account the explicit and implicit models of both the patient and the therapist may lead to misunderstandings, aggressive behaviors, anxious reactions, and thus hamper or even disrupt the patient-therapist relationship.

     

胫,股骨内压与膝关节疼痛关系的研究和治疗方法探讨

作者对膝关节痛和休息痛病人21例做了股、胫骨内压和关节镜检查,其均值股骨髁0.143±0.01kPa,16例(76.19％)超过对照组0.130kPa(P<0.01);胫骨髁0.180±0.022kPa,18例(85.7％),超过对照组0.105kPa。同时测量膝关节腔内压21例。均值为0.135±0.035kPa,18例(85.7％)高于对照组0.120kPa。认为骨内压增高是引起膝关节痛的原因。本文还就膝关节特发性骨内高压症的临床表现、镜下特点、个体临界骨内压和治疗方法进行了探讨。     

THE INTRODUCTION OF PATIENT-CONTROLLED ANALGESIA INTO AN ISOLATED RURAL HOSPITAL

This study investigated the feasibility of using patient-controlled analgesia (PCA) effectively in a small 70 bed isolated rural hospital. The tirst 50 patients to use a Bard PCA 1, in the Port Lincoln Hospital, South Australia, were studied. The patients consumed morphine at a mean rate of 1.24 mg/h and used PCA for a mean of 48 h. Thirty-eight per cent of patients required treatment for nausea and other complications which is similar to the rate of those in other published series. Visual analogue pain scores showed excellent pain control, generally without evidence of oversedation; however, there was one episode of respiratory depression. Seventy-eight per cent of patients reported that their pain was relieved most or all of the time. The study demonstrated that a PCA service provided by nursing staff, the GP anaesthetist and rural surgeons is feasible in an isolated rural hospital.     

AAEM minimonograph #43: Neuromuscular problems in the performing arts

Over the past 10–15 years, there has been increasing interest in the health problems of performing artists. In this review, I will discuss the major playing-related disorders seen in instrumental musicians. Among the 672 instrumentalists evaluated, the major diagnoses identified included musculoskeletal disorders in 64%, peripheral nerve problems in 22.5%. and focal dystonia in 7%. Sixty percent of instrumentalists were female although males predominate in the group with focal dystonia. The average age of those evaluated was 32 years. Among musculoskeletal disorders overuse syndrome is the most common. Frequent peripheral nerve disorders include thoracic outlet syndrome, carpal tunnel syndrome, and ulnar neuropathy. A characteristic distribution of symptoms and signs is identified for each instrument group. Electrodiagnostic studies are an important part of the evaluation of these disorders. With carefully designed treatment, the majority of instrumental musicians can be returned to full and pain-free playing activities. The success rate is highest in some entrapment neuropathies but remains low in focal dystonia. © 1994 John Wiley & Sons, Inc.     

Intraperitoneal bupivacaine for analgesia after laparoscopic cholecystectomy

Background The effects of intraperitoneal administration of bupivacaine on pain after laparoscopic cholecystectomy were studied in a prospective, double-blind, randomised trial. Methods: Eighty ASA 1 and 2 patients were randomly assigned to one of two groups. Immediately after pneumoperi-toneum was obtained patients in group 1 were given 15 ml of 0.5% bupivacaine injected under direct vision into the hepato-diaphragmatic space, near and above the hepato-duodenal ligament and above the gallbladder. At the end of operation another 15 ml of bupivacaine was injected. Patients in group 2 were given 15 ml of 0.9% saline solution in a similar fashion. Postoperative pain was assessed using a visual analogue scale (VAS 100 mm) at 0.5,4, 8,12 and 24 h after surgery. Analgesic consumption was also recorded.     

Preoperative infiltration of the surgical area enhances postoperative analgesia of a combined low–dose epidural bupivacaine and morphine regimen after upper abdominal surgery

In a randomized, blinded trial we assessed the value of adding preoperative infiltration of the surgical area with bupivacaine to a low dose epidural regimen for postoperative pain treatment. Forty–nine patients scheduled for major upper abdominal surgery during combined thoracic epidural (bupivacaine + morphine) and general anaesthesia were studied. Postoperative analgesia was epidural bupivacaine 10 mg hr^-1 + morphine 0.2 mg hr^-1 for 72 h. The patients randomly received preoperative infiltration of the surgical area with bupivacaine 0.25%, 40 ml (group I); or no infiltration (group II). Pain was evaluated at rest, during cough and during mobilization six and eight h after start of surgery, and at 8 a.m. and 4 p.m. on the following days until 72 h after start of surgery. The sensory level of analgesia was evaluated by pin prick. We found no difference between the two groups during rest and cough. However, during mobilization group I had lower pain scores compared to group II ( P < 0.05). There was a significant reduction in the need for supplemental intramuscular morphine in the treatment group compared to the control group ( P <0.05). Thus an enhanced analgesic effect was demonstrated by adding preoperative infiltration of the surgical area with local anaesthetic to a low dose epidural bupivacaine/morphine regimen after upper abdominal surgery.

The relationship between activity and pain in patients 6 months after lumbar disc surgery: Do pain-related coping modes act as moderator variables?

BACKGROUND: In LBP patients, the relationship between pain and physical activity remains unclear. Whereas a negative relationship between pain and self-reported physical activity was found, this relation disappeared in the case of overt behavioral data (e.g., accelerometer). Cognitive-behavioral models of the development of chronic pain suggest subgroups with signs of physical underuse and overuse. AIMS: To examine if patients with pain-related adaptive, endurance and fear-avoidance coping differ in pain, self-reported physical function and overt physical activity 6 months after disc surgery. METHODS: 24 patients completed questionnaires (Von Korff chronic pain grade (CPG), Kiel pain inventory (KPI), Funktionsfragebogen Hannover-Rücken FFbH-R) and underwent an 8-h accelerometer assessment in their daily life (physical activity level (PAL), number of constant postures (CP)). The KPI differed between adaptive coping (AC) (N=9), fear avoidance coping (FAC) (N=1) and endurance coping (EC) (N=14). RESULTS: In the whole group, pain intensity was negative related to self-reported physical activity whereas PAL and CP displayed no correlation with pain. EC patients showed significantly higher pain scores and lower self-reported physical functioning compared to AC but the same level of PAL and furthermore, a significantly higher number of CPs in daily life. The visual inspection of the FAC patient revealed also high pain, low physical functioning and low overt physical activity. CONCLUSIONS: The assessment of pain-related coping modes yielded an important differentiation between subgroups of LBP patients 6 months after surgery. Endurance copers displayed signs of overuse in their daily behavior in spite of pain than adaptive copers. The one fear avoidance coper tends to do less physical activity in the sense of underuse.
