RESUMEN
OBJECTIVES: The French government voted a new law in February 2016 called the Claeys-Leonetti Law, which established the right to deep and continuous sedation, confirmed the ban on euthanasia and ruled out physician-assisted suicide. The aim of this work was to gather the opinion of patients on continuous sedation and the legalisation of medical assistance in dying and to explore determinants associated with favourable and unfavourable opinions. METHODS: This was a French national prospective multicentre study between 2016 and 2020. RESULTS: 331 patients with incurable cancer suffering from locally advanced or metastatic cancer in 14 palliative care units were interviewed. 48.6% of participants expressed a favourable opinion about physician-assisted suicide and 27.2% an unfavourable opinion about its legalisation. Regarding euthanasia, 52% of patients were in favour of its legalisation. In univariate analysis, the only factor determining opinion was belief in God. CONCLUSIONS: While most healthy French people are in favour of legalising euthanasia, only half of palliative care patients expressed this opinion. Medical palliative care specialists were largely opposed to euthanasia. The only determining factor identified was a cultural factor that was independent of the other studied variables. This common factor was found in other studies conducted on cohorts from other countries. This study contributes to the knowledge and thinking about the impact of patients' personal beliefs and values regarding their opinions about euthanasia and assisted suicide. TRIAL REGISTRATION NUMBER: NCT03664856.

INTRODUCTION: Transabdominal chorionic villus sampling (CVS) is an invasive procedure for prenatal diagnosis reported to be associated with anxiety and pain. In this context, the need for analgesia during CVS has been considered useful. Even though several authors have been interested in pain management during amniocentesis, no study has been published on pain reduction during CVS. Our objective was to evaluate pain and anxiety management during transabdominal CVS using nitrous oxide (N2 O) and local anesthesia. MATERIAL AND METHODS: In a randomized controlled noninferiority trial, self-administered nitrous oxide (N2 O) inhalation (equimolar premix of oxygen and nitrous oxide) was compared with local anesthesia (1% lidocaine) before CVS. Primary outcome was pain and secondary outcome was anxiety, both measured on a visual analog scale 30-60 minutes before, immediately after (5-10 minutes) and 30-60 minutes after CVS. With a statistical power of 90%, type I error of 5% and two-sided test and potential exclusions, a sample size of 96 patients per group was enrolled and randomized. No patient was enrolled before the trial registration date. RESULTS: From 13 March 2013 through 10 February 2015, 192 patients (96 per group) were screened and randomized. Most characteristics were similar across groups. Pain in the N2 O group was 2.65 ± 0.22 vs 3.32 ± 0.26 in local anesthesia group [mean ± standard error of mean (SEM)]. Mean anxiety in the N2 O group was 3.17 ± 0.27 vs 5.19 ± 0.30 in the local anesthesia group. CONCLUSION: N2 O was as efficient and even superior to local anesthesia for both pain and anxiety reduction during CVS, as the 95% confidence intervals were both below the prespecified noninferiority margin of 0.8 and below zero.

BACKGROUND: The literature has described the use of ketamine as an adjuvant treatment for opioid-refractory cancer pain. None of these studies have used the drug in a palliative care patient population. AIMS: The primary objective of the study was to assess the efficacy of continuous intravenous infusion of ketamine in patients suffering from cancer pain refractory to opiates who had been admitted to palliative care units. Secondary objectives were to assess patients' satisfaction with and tolerance of ketamine. METHODS: A randomized, double-blind, placebo-controlled study was designed, and the study setting included seven French adult palliative care units. Inclusion criteria were age ≥18 years, and cancer pain refractory to standard opiates. Evaluations were conducted at randomization (baseline), at ketamine or placebo introduction time (T0), and at 2 hours (T1), 24 hours (T2), and 48 hours (T3) after T0. The primary evaluation criterion was pain efficacy assessed using a patient self-rated Numeric Pain Intensity Scale (NPIS) at T1. The main secondary evaluation criteria were daily morphine dose, symptom evaluation (Edmonton Symptom Assessment Scale [ESAS]), and patient satisfaction (Pain Treatment Satisfaction Scale [PTSS]). RESULTS: Twenty patients were analyzed (11 received ketamine and 9 received placebo). Self-reported pain did not differ between the two groups, as the symptoms continued to evolve during the study period. The tolerance for ketamine was satisfactory. CONCLUSION: The present study did not confirm the efficacy of the ketamine-morphine combination in refractory cancer pain. The results suggest that specific populations could be "good responders" for this therapeutic approach. Further studies should be performed that take into account the difficulties of conducting clinical research in the palliative care context.
