Quand il n’y en a plus mais qu’on en veut encore: les prédicteurs de besoins excessifs en analgésie postopératoire intraveineuse contrôlée par le patient
Background: Psychosocial factors governing the use of postoperative, intravenous patient-controlled analgesia (PCA) have received little attention in spite of the fact that PCA is the most common modality for managing pain after surgery. The motivation behind requests for analgesia during lockout periods is not known. Unrelieved pain and need for pain medication are obvious reasons but other factors may be involved. The aim of the present study was to predict PCA lockout interval demands based on preoperative psychosocial factors.
Methods: Approximately one week before major abdominal gynecologic surgery, 117 women completed the impact of events scale (IES) measuring intrusive thoughts and avoidant behaviours. Pain was measured by visual analogue scale at three, six, 12, 24 and 48 hr after surgery. Measures of anxiety and negative affect were obtained 24 and 48 hr after surgery. Cumulative morphine consumption and every PCA demand (drug delivered and not delivered) were downloaded from the PCA pump.
Results: Multiple regression analyses revealed that preoperative intrusive thoughts and avoidant behaviours about the upcoming surgery positively predicted PCA lockout interval demands after controlling for postoperative pain, morphine consumption, anxiety, and negative affect (R2 = 0.45; P < 0.0001). Path analysis showed a direct pathway from preoperative IES scores to lockout interval demands (β = 0.23, P = 0.002) which was not associated with untreated pain, anxiety, or negative affect.
Conclusions: Excessive demands for postoperative intravenous- PCA morphine during lockout intervals appear to reflect, in part, poor preoperative adaptation to surgery involving intrusive thoughts and avoidant behaviours about the upcoming surgery.Les facteurs psychosociaux régissant l’usage d’analgésie postopératoire intraveineuse contrôlée par le patient (ACP) n’ont reçu que peu d’attention, malgré le fait que l’ACP constitue le mode le plus fréquent de prise en charge de la douleur après une chirurgie. Les motivations derrière les demandes d’analgésie durant les intervalles d’interdiction ne sont pas connues. Bien qu’une douleur qui n’est pas soulagée et le besoin de médicaments anti-douleur constituent des raisons évidentes, d’autres facteurs pourraient jouer un rôle. L’objectif de cette étude était de prédire les demandes d’ACP pendant les intervalles d’interdiction sur la base de facteurs psychosociaux préopératoires.Supported by Grant NS35480 from the National Institutes of Health, Bethesda, Maryland,
