Post-partum relapse in women with multiple sclerosis after neuraxial labour analgesia or neuraxial anaesthesia: A multicentre retrospective cohort study.

BACKGROUND: The proportion of women with multiple sclerosis experiencing a relapse in the post-partum period after neuraxial labour analgesia or neuraxial anaesthesia remains uncertain. This study aimed to assess the association between neuraxial labour analgesia or neuraxial anaesthesia and the occurrence of relapse during the first three months post-partum. METHODS: In this retrospective cohort study, cases of women with a diagnosis of multiple sclerosis delivering between January 2010 and April 2015 were analysed. Demographic, anaesthetic and obstetric characteristics, occurrence and number of relapses in the year preceding pregnancy, during pregnancy, and the first three post-partum months, were recorded. Logistic regression analyses were performed for the identification of factors associated with the occurrence of post-partum relapse. RESULTS: A total of 118 deliveries in 104 parturients were included, these were 78 (66%) vaginal deliveries and 40 (34%) caesarean deliveries. Neuraxial analgesia was provided in 50 deliveries, and neuraxial anaesthesia in 46 deliveries; no neuraxial anaesthesia or analgesia was administered in remaining 22 deliveries. Post-partum relapse occurred in 31 women (26%). There was no association between obstetric or anaesthetic characteristics and post-partum relapse. Both the occurrence and number of relapses prior to and during pregnancy, and the time between last relapse and delivery, were significantly associated with post-partum relapse in univariate analysis. The occurrence of relapse within the year preceding the pregnancy was the sole independent factor associated with post-partum relapse. CONCLUSION: Neuraxial procedures were not associated with increased rate of post-partum relapse; only disease activity prior to pregnancy was predictive of post-partum relapse.

Laparoscopic adnexectomy under regional anaesthesia: It is possible!

At present, the majority of laparoscopic operations are performed under general anaesthesia, as it controls surgical pain and improves patient comfort using pneumoperitoneum and the Trendelenburg position. However, some laparoscopic procedures, such as adnexectomies, can potentially be performed under epidural anaesthesia with a purposefully selected and motivated patient managed by prepared surgical and anaesthesia care teams working together effectively. This study reports the case of a 63-year-old female patient with major respiratory failure who underwent laparoscopic bilateral adnexectomies under epidural anaesthesia.

Does programmed intermittent epidural bolus improve childbirth conditions of nulliparous women compared with patient-controlled epidural analgesia?: A multicentre, randomised, controlled, triple-blind study.

BACKGROUND: Epidural analgesia may change the mechanics of childbirth. These changes are related to the concentration of the local anaesthetic used epidurally but probably also to its mode of delivery into the epidural space. OBJECTIVE: To determine whether the administration of programmed intermittent epidural boluses (PIEB) improves the mechanics of second-stage labour compared with patient-controlled epidural analgesia (PCEA) with a background infusion. DESIGN: A randomised, controlled, triple-blind study. SETTING: Multicentre study including four level III maternity units, January 2014 until June 2016. PATIENTS: A total of 298 nulliparous patients in spontaneous labour were randomised to a PIEB or PCEA group. INTERVENTION: After epidural initiation with 15 ml of 0.1% levobupivacaine containing 10 µg of sufentanil, patients received either an hourly bolus of 8 ml (PIEB) or a continuous rate infusion of 8 ml h (PCEA): the drug mixture used was levobupivacaine 0.1% and sufentanil 0.36 µg ml. MAIN OUTCOME MEASURES: The primary outcome was a composite endpoint of objective labour events: a posterior occiput position in the second stage, an occiput position at birth, waiting time at full cervical dilatation before active maternal pushing more than 3 h, maternal active pushing duration more than 40 min, and foetal heart rate alterations. Vaginal instrumental delivery rates, analgesia and motor blockade scores were also recorded. RESULTS: From the 298 patients randomised, data from 249 (124 PIEB, 125 PCEA) were analysed. No difference was found in the primary outcome: 48.0% (PIEB) and 45.5% (PCEA) of patients, P = 0.70. In addition, no difference was observed between the groups for each of the individual events of the composite endpoint, nor in the instrumental vaginal delivery rate, nor in the degree of motor blockade. Despite an equivalent volume of medication in the groups, a significantly higher analgesia score at full dilatation was observed in the PIEB group, odds-ratio = 1.9 (95% confidence interval, 1.0 to 3.5), P = 0.04. CONCLUSION: The mechanics of the second stage did not differ whether PIEB or PCEA was used. Analgesic conditions appeared to be superior with PIEB, especially at full dilation.

Transcultural adaptation and French validation of the Pain Sensitivity Questionnaire.

PURPOSE: To validate a French translation of the Pain Sensitivity Questionnaire (PSQ), which is a valuable tool to predict an individual's natural disposition to feel pain that could be used after surgery. METHODS: We studied content validity, internal consistency, convergent validity (anxiety, depression and catastrophism) and test-retest reliability of the French version of the PSQ (PSQ-F) in 146 patients either before scheduled surgery or during pregnancy; then, convergent and concurrent validity in 85 healthy volunteers submitted to nociceptive tests. RESULTS: Internal consistency of the PSQ-F was found to be excellent, with Cronbach's α at 0.866, 0.886, and 0.927, respectively for its "minor", "moderate" and "total" scores. Test-retest reliability was significant, with intraclass correlation coefficients at 0.629, 0.629, and 0.635, respectively for the above- mentioned scores. These three scores correlated with anxiety, depression and catastrophizing scores in patients, but not in healthy volunteers, possibly because of low and few variant psychometric scores in this group. They were inversely correlated to the temperature needed to evoke heat pain rated 6 out of 10, but not to the mechanical pain threshold (electronic von Frey), nor to the heat pain threshold. Finally, they directly correlated to the pain induced by the cold pressor test (minor and total scores only). DISCUSSION: This validated version can now be used by French-speaking researchers and physicians. TRIAL REGISTRATION: www.ClinicalTrials.gov (NCT03113903); 14 April, 2017.

RéSUMé: OBJECTIF: Valider une version en langue française du Pain Sensitivity Questionnaire (PSQ), qui permet d'identifier la sensibilité naturelle d'un individu à la douleur, ce qui pourrait être applicable après une chirurgie. MéTHODE: Nous avons étudié la validité de structure interne, la validité convergente (anxiété, dépression et catastrophisme) et la reproductibilité par test-retest de la version française du PSQ (PSQ-F) chez 146 patients en situation préopératoire ou en cours de grossesse, puis la validité convergente et de structure contre critère externe chez 85 sujets volontaires sains soumis à des tests nociceptifs. RéSULTATS: La consistance interne du PSQ-F était excellente avec des α de Cronbach égaux à 0,866, 0,886 et 0,927, respectivement pour ses scores « mineur ¼, « modéré ¼ et « total ¼. La reproductibilité était satisfaisante, avec des coefficients de corrélation intra-classe, respectivement à 0,629, 0,629 et 0,635. Ces trois scores étaient corrélés à l'anxiété, la dépression et le catastrophisme, mais pas chez les volontaires sains qui avaient des scores psychométriques bas et peu variables. Ils étaient anti-corrélés au seuil de nociception thermique chaud en épreuve supra-liminale, mais pas au seuil de nociception mécanique ponctuelle, ni au seuil de nociception thermique chaud en épreuve liminale. Enfin, les scores « mineur ¼ et « total ¼ étaient corrélés à la douleur moyenne ressentie à l'immersion du pied en eau froide. CONCLUSION: Cette version validée peut être utilisée par les chercheurs et cliniciens francophones. ENREGISTREMENT DE L'éTUDE: www.ClinicalTrials.gov (NCT03113903); le 14 avril 2017.

Effects of low intraperitoneal pressure and a warmed, humidified carbon dioxide gas in laparoscopic surgery: a randomized clinical trial.

Laparoscopic surgery technology continues to advance. However, much less attention has been focused on how alteration of the laparoscopic surgical environment might improve clinical outcomes. We conducted a randomized, 2 × 2 factorial trial to evaluate whether low intraperitoneal pressure (IPP) (8 mmHg) and/or warmed, humidified CO2 (WH) gas are better for minimizing the adverse impact of a CO2 pneumoperitoneum on the peritoneal environment during laparoscopic surgery and for improving clinical outcomes compared to the standard IPP (12 mmHg) and/or cool and dry CO2 (CD) gas. Herein we show that low IPP and WH gas may decrease inflammation in the laparoscopic surgical environment, resulting in better clinical outcomes. Low IPP and/or WH gas significantly lowered expression of inflammation-related genes in peritoneal tissues compared to the standard IPP and/or CD gas. The odds ratios of a visual analogue scale (VAS) pain score >30 in the ward was 0.18 (95% CI: 0.06, 0.52) at 12 hours and 0.06 (95% CI: 0.01, 0.26) at 24 hours in the low IPP group versus the standard IPP group, and 0.16 (95% CI: 0.05, 0.49) at 0 hours and 0.29 (95% CI: 0.10, 0.79) at 12 hours in the WH gas group versus the CD gas group.

Ovarian thrombosis and uterine synechiae after arterial embolization for a late postpartum haemorrhage.

BACKGROUND: We report two unusual separate complications after uterine artery embolization for a late postpartum haemorrhage. This report appeared important to us in view of the apparent absence of any other publications on this topic. CASE PRESENTATION: We report the case of a 25-year-old woman, gravida 3, para 1, admitted for uterine bleeding 7 days after a spontaneous delivery at term, in our university hospital. A suction curettage and then, after persistent bleeding, uterine artery embolization were necessary. Immediately after the embolization, a bilateral ovarian thrombosis occurred, subsequently followed by amenorrhea, due to uterine synechiae, and depression. Hysteroscopic surgery was performed to remove the adhesions. A complete work-up for thrombophilia showed a heterozygous mutation of the factor V gene R506Q. The pathology examination found subinvolution of the placental bed. One month after treatment of the synechiae (and insertion of a copper IUD for contraception), the woman's menstrual cycle returned to normal. Her clinical examination 19 months later was normal. CONCLUSIONS: This case teaches us that one rare complication can hide another! It is important to consider the diagnosis of subinvolution of the placental bed in cases of late PPH and to know the complications associated with vascular artery embolization in order to provide the most rapid and least invasive treatment.

Placenta accreta: management with uterine artery embolization in 17 cases.

PURPOSE: To report on the management of placenta accreta with uterine artery embolization (UAE) and to analyze the outcomes. MATERIALS AND METHODS: A retrospective study was performed over a 128-month period of all women with placenta accreta who underwent UAE in a single center. Seventeen patients were included, and they were further divided into two groups: a preventive group (diagnosis was made in the prenatal period, n = 6) and a curative group (diagnosis was made during delivery, n = 11). The mean patient age was 34.6 years +/- 5.5 in the preventive group and 31.4 years +/- 4.3 in the curative group. The mean term of pregnancy was 35 weeks +/- 2 of amenorrhea in the preventive group and 38 weeks +/- 2 in the curative group. RESULTS: The primary success of embolization was 100% in both groups. In the preventive group, massive bleeding occurred in a patient 2 days after unsuccessful manual placenta delivery resulted in an hysterectomy; in a second case, delayed bleeding (2 months after the procedure) was controlled with a second embolization. There were no episodes of repeat bleeding in the curative group. In the preventive group, two patients presented with uterine scarring, with synechiae in one and endometrial atrophy in the other. In the curative group, one patient presented with secondary amenorrhea. The delay before embolization was significantly different in the two groups (23.3 minutes +/- 5.1 in the preventive group vs 73 minutes +/- 44.7 in the curative group, P < .01), and total blood loss was 0.7 L +/- 0.8 in the preventive group and 2.6 L +/- 1.2 in the curative group (P < .01). CONCLUSIONS: Prenatal diagnosis of placenta accreta permits its preventive management, which reduces time to embolization and blood loss.
