The role of central serotonergic markers and estradiol changes in perinatal mental health.

OBJECTIVE: Women have an increased risk for mental distress and depressive symptoms in relation to pregnancy and birth. The serotonin transporter (SERT) may be involved in the emergence of depressive symptoms postpartum and during other sex-hormone transitions. It may be associated with cerebrospinal fluid (CSF) levels of the main serotonin metabolite 5-hydroxyindolacetic acid (5-HIAA). In 100 healthy pregnant women, who were scheduled to deliver by cesarean section (C-section), we evaluated 5-HIAA and estradiol contributions to mental distress 5 weeks postpartum. METHODS: Eighty-two women completed the study. CSF collected at C-section was analyzed for 5-HIAA, with high performance liquid chromatography. Serum estradiol concentrations were quantified by liquid chromatography tandem mass spectrometry before C-section and postpartum. Postpartum mental distress was evaluated with the Edinburgh Postnatal Depression Scale (EPDS). Associations between EPDS, 5-HIAA, and Δestradiol were evaluated in linear regression models adjusted for age, parity and SERT genotype. RESULTS: Higher levels of postpartum mental distress symptoms were negatively associated with a large decrease in estradiol concentrations (ßΔE2  = 0.73, p = 0.007) and, on a trend level, positively associated with high antepartum 5-HIAA levels (ß5-HIAA  = 0.002, p = 0.06). CONCLUSION: In a cohort of healthy pregnant women, postpartum mental distress was higher in women with high antepartum 5-HIAA (trend) and lower in women with a large perinatal estradiol decrease. We speculate that high antepartum 5-HIAA is a proxy of SERT levels, that carry over to the postpartum period and convey susceptibility to mental distress. In healthy women, the postpartum return to lower estradiol concentrations may promote mental well-being.

[Advanced labour pain relief].

Delivery and labour pain is normally the most painful event in a woman's lifetime. Physical and psychological factors may influence the severity of labour pain, and labour pain relief is an important issue for the obstetric anaesthetist. We describe the current most effective pharmacological techniques used for labour analgesia: systemically with remifentanil and regionally with epidural analgesia.

[Sectio and Brugada syndrome].

Brugada syndrome (BS) is an inherited cardiac disease with increased risk of ventricular tachyarrythmias, cardiac arrest and sudden death. BS is diagnosed on various criteria including specific electrocardiographic abnormalities in a structurally normal heart. Many drugs have been reported to induce fatal arrhythmias in patients with BS and in particular sodium channel blockers i.e. local anaesthetics such as bupivacaine. We report the anaesthetic management of two women with BS during caesarean section and provide a general discussion on the use of bupivacain for neuraxial blockade for patients with BS.

Hemostatic resuscitation in postpartum hemorrhage - a supplement to surgery.

BACKGROUND: Postpartum hemorrhage is a potentially life-threatening albeit preventable condition that persists as a leading cause of maternal death. Identification of safe and cost-effective hemostatic treatment options remains crucial as a supplement to surgery and uterotonic agents. OBJECTIVE: This review summarizes the background, current evidence and recommendations with regard to the role of fibrinogen, tranexamic acid, prothrombin complex concentrate, desmopressin, and recombinant factor VIIa in the treatment of patients with postpartum hemorrhage. The benefits and evidence behind traditional standard laboratory tests and viscoelastic hemostatic assays, i.e. thromboelastography TEG(®) and thromboelastometry ROTEM(®) , are discussed. In addition we assess and elaborate on the current paradigm and evidence for transfusion of these patients. DATA SOURCES: Publications between 1994 and 2014 were identified from PubMed, EMBASE, Cochrane Library databases, and ClinicalTrial.gov. RESULTS: Viscoelastic hemostatic assays were found to provide a real-time continuum of coagulation and fibrinolysis when introduced as a supplement in transfusion management of postpartum hemorrhage. Fibrinogen should be considered when hypofibrinogenemia is identified. Early administration of 1-2 g tranexamic acid is recommended, followed by an additional dose in cases of ongoing bleeding. Uncontrolled hemorrhage requires early balanced transfusion. CONCLUSION: Despite the lack of conclusive evidence for optimal hemostatic resuscitation in postpartum hemorrhage, the use of viscoelastic hemostatic assays, fibrinogen, tranexamic acid and balanced transfusion therapy may prove to be potentially pivotal in the treatment of postpartum hemorrhage.

'In situ simulation' versus 'off site simulation' in obstetric emergencies and their effect on knowledge, safety attitudes, team performance, stress, and motivation: study protocol for a randomized controlled trial.

BACKGROUND: Unexpected obstetric emergencies threaten the safety of pregnant women. As emergencies are rare, they are difficult to learn. Therefore, simulation-based medical education (SBME) seems relevant. In non-systematic reviews on SBME, medical simulation has been suggested to be associated with improved learner outcomes. However, many questions on how SBME can be optimized remain unanswered. One unresolved issue is how 'in situ simulation' (ISS) versus 'off site simulation' (OSS) impact learning. ISS means simulation-based training in the actual patient care unit (in other words, the labor room and operating room). OSS means training in facilities away from the actual patient care unit, either at a simulation centre or in hospital rooms that have been set up for this purpose. METHODS AND DESIGN: The objective of this randomized trial is to study the effect of ISS versus OSS on individual learning outcome, safety attitude, motivation, stress, and team performance amongst multi-professional obstetric-anesthesia teams.The trial is a single-centre randomized superiority trial including 100 participants. The inclusion criteria were health-care professionals employed at the department of obstetrics or anesthesia at Rigshospitalet, Copenhagen, who were working on shifts and gave written informed consent. Exclusion criteria were managers with staff responsibilities, and staff who were actively taking part in preparation of the trial. The same obstetric multi-professional training was conducted in the two simulation settings. The experimental group was exposed to training in the ISS setting, and the control group in the OSS setting. The primary outcome is the individual score on a knowledge test. Exploratory outcomes are individual scores on a safety attitudes questionnaire, a stress inventory, salivary cortisol levels, an intrinsic motivation inventory, results from a questionnaire evaluating perceptions of the simulation and suggested changes needed in the organization, a team-based score on video-assessed team performance and on selected clinical performance. DISCUSSION: The perspective is to provide new knowledge on contextual effects of different simulation settings. TRIAL REGISTRATION: ClincialTrials.gov NCT01792674.

[Most anaesthetics can be used without damaging effects of the breastfed child]. / De fleste anæstesimidler kan bruges uden skadelig påvirkning af barnet ved amning.

Breastfeeding women who undergo general anaesthesia often receive conflicting recommendations regarding the need to discard their milk before resumption of breastfeeding. This narrative review describes the sparse evidence to support the current practice of discarding milk as advocated by many physicians. However, individual drugs such as diazepam, morphine, codeine and pethidine should be avoided when possible and otherwise only be administered as single doses with observation of the child. There is an urgent need for high-quality research before sufficient light can be shed on this topic.

[Treatment of placenta percreta requires a multidisciplinary approach]. / Behandling af placenta percreta kræver involvering af flere specialer.

Placenta percreta is a rare life-threatening obstetrical condition, often resulting in severe haemorrhage and hysterectomy. The incidence seems to be increasing, probably secondary to the increase in caesarean section rates. We present a protocol for an elective multidisciplinary approach with proactive management to reduce haemorrhage and allow appropriate surgery, which imply a low maternal and fetal morbidity as well as maintained fertility.
