Resume En reponse aux questionnements concernant l’intensite des soins a mettre en place pour les patients atteints d’une maladie grave, en particulier pour les cancers bronchiques metastatiques, une « fiche d’aide a la decision en cas d’aggravation d’un patient atteint d’une maladie grave » a ete mise en place au centre hospitalo-universitaire (CHU) de Grenoble. Ce document a ete etabli dans le respect de la loi de 2005 relative aux droits des malades et a la fin de vie. Il rappelle l’importance de prendre en consideration la volonte du patient en cas d’aggravation aigue de son etat. En fonction de son avis et de l’experience de l’equipe medicale et soignante qui le suit habituellement, un niveau d’intensite de soins a instaurer, le cas echeant, est propose. Ces suggestions servent d’aide a la decision pour le medecin de garde responsable du patient. Cet outil renforce la relation « medecin–malade » du fait de la participation du patient aux decisions qui le concernent et permet une prise en charge optimale et raisonnable du patient lorsqu’il presente une defaillance d’organe. Une evaluation prospective sur l’interet de l’outil en oncologie thoracique est prevue.

Background Epidural clonidine produces analgesia without motor impairment, and is associated with a local anesthetic-sparing effect during labor. The authors have recently demonstrated that epidural neostigmine initiates selective labor analgesia devoid of adverse effects. Both drugs possess common analgesic mechanisms mediated through spinal acetylcholine release. This study evaluates their epidural combination in parturients. Methods At the beginning of labor, parturients were randomly allocated to one of five groups to receive one of the following after a test dose: 150 microg epidural clonidine, 750 microg neostigmine, or 75 microg clonidine combined with 250, 500, or 750 microg neostigmine. A pain score (visual analog scale, 0-100) was recorded before administration and at regular intervals until request for a supplemental injection. Subsequent analgesia was provided by continuous epidural infusion of ropivacaine. Results Parturients did not differ regarding demographic data and initial pain score. Clonidine 150 microg , neostigmine 750 microg , and 75 microg clonidine plus 250 microg neostigmine produced ineffective and short-lasting effects. Clonidine 75 microg plus 500 microg neostigmine and 75 microg clonidine plus 750 microg neostigmine presented comparable durations of 90 +/- 32 and 108 +/- 38 min (mean +/- SD), respectively, and final analgesic efficacies, with 72.2% and 84%, respectively, of the parturients reporting a visual analog scale score of less than 30 out of 100 after 30 min. Ropivacaine use was significantly reduced in all clonidine groups (average, 9.5 mg/h) in comparison with neostigmine alone (17 +/- 3 mg/h). No adverse effects were observed for 75 mug clonidine combined with any dose of neostigmine while maternal sedation (20%) and hypotension (33%) occurred with 150 microg clonidine alone. Conclusions Epidural clonidine, 75 microg , with 750 microg neostigmine is an effective combination to initiate selective labor analgesia without adverse effects. Clonidine use further reduces local anesthetic consumption throughout the course of labor.

We previously demonstrated the effectiveness of epidural sufentanil and the cholinesterase inhibitor, neostigmine, to initiate selective labor analgesia. Because the traditional lidocaine plus epinephrine test dose (TD) may alter the effect of subsequent epidural drugs, we undertook this investigation to evaluate the impact of a lidocaine TD on analgesia from a combination of epidural neostigmine plus sufentanil administered in early labor. Eighty healthy parturients were randomly allocated to two groups to receive a 3 mL-TD, either lidocaine 2%-epinephrine (1:200,000) or saline-epinephrine (1:200,000), followed 3 min later by epidural neostigmine 500 microg plus sufentanil 10 microg. Pain scores were recorded for 30 min after injection, as was the time elapsed from initial bolus until request for supplemental analgesia. Thirty minutes after injection, adequacy of motor function was evaluated by the parturient's ability to sit, stand up, bend her knees, and walk. Lidocaine TD hastened the onset (5 min vs 15 min) and increased duration (122 +/- 53 min vs 98 +/- 54 min; P = 0.02) of analgesia from epidural neostigmine plus sufentanil bolus. In contrast, the TD did not significantly impair the ability to sit, stand up, or bend the knees. The ability to ambulate, however, was reduced (57% vs 82%; P = 0.04). In conclusion, a traditional lidocaine TD significantly enhances the analgesic effect from the epidural neostigmine plus sufentanil combination, but affects ambulation in early labor.
