[Intracerebroventricular infusion of morphine, bupivacaine and clonidine for the management of refractory neoplasic pain in a palliative care setting : a case report]. / Administration intracérébroventriculaire de morphine, bupivacaïne et clonidine pour la gestion de la douleur réfractaire d'origine néoplasique en soins palliatifs.

Intracerebroventricular (ICV) infusion of morphine is a well-known technique to relieve intractable neoplasic pain when conventional analgesic strategies reach their limits. Through this case report, we present indications, assets, and drawbacks of this procedure in such conditions. We also describe the adaptation of the systemic analgesic treatment to allow discharge from the hospital to home settings. Thanks to the ICV infusion of a mixture of morphine, bupivacaine and clonidine, the patient was weaned from oral opioid medications and reached an acceptable level of comfort. This allowed him to be discharged from the hospital to go back home with a specific setting of mobile palliative care structure. The patient's family followed training about the device to prevent any technical trouble and to react in case of unwanted events.

L'administration de morphine intracérébroventriculaire (ICV) est une technique bien connue pour traiter les douleurs néoplasiques insoutenables lorsqu'un traitement antalgique conventionnel atteint ses limites. A travers un cas clinique, nous présentons les indications, les atouts et les inconvénients de cette procédure dans de telles conditions. Nous décrivons aussi l'adaptation du traitement antalgique per os après implantation du cathéter. Grâce à l'infusion ICV d'un mélange de morphine, de bupivacaïne et de clonidine, le patient a été sevré totalement des dérivés opioïdes oraux et a atteint un niveau de confort acceptable pour rentrer à domicile avec une structure mobile de soins palliatifs mise en place. L'entourage du patient a bénéficié de séances d'information pour prévenir les problèmes techniques liés au dispositif et pour réagir en cas d'incident.

Transversus abdominis plane block or intravenous lignocaine in open prostate surgery: a randomized controlled trial.

BACKGROUND AND OBJECTIVES: Transversus abdominis plane block (TAP) and intravenous lignocaine are two analgesic techniques frequently used after abdominal surgery. We hypothesized that these two techniques improve post-operative analgesia after open prostate surgery and sought to compare their efficacy on immediate post-operative outcome after open prostate surgery. METHODS: After ethics committee approval, 101 patients were enrolled in this prospective study and randomly allocated to receive bilateral ultrasound-guided TAP (n = 34), intravenous lignocaine (n = 33) or placebo (n = 34). In addition, intravenous paracetamol was given every 6 h. The primary endpoint was the cumulative opioid consumption during the first 48 post-operative hours (median[IQR]). Secondary endpoints included pain scores at rest and upon coughing, need for rescue tramadol, incidence of post-operative nausea and vomiting (PONV), recovery of bowel function and incidence of bladder catheter-related discomfort. RESULTS: Cumulative piritramide consumption after 48 h was 28 [23] mg in the control group, 21 [29] mg in the TAP group and 21 [31] mg in the lignocaine group (P = 0.065). There was no significant difference in post-operative pain scores between groups. The proportions of patients requiring rescue tramadol, experiencing PONV or bladder catheter-related discomfort were similar in each group. Recovery of bowel function was also similar in the three groups. CONCLUSIONS: Our study suggests that TAP block and intravenous lignocaine do not improve the post-operative analgesia provided by systematic administration of paracetamol after open prostatectomy.
