Abstract
Purpose This guideline aims to summarize the current state of knowledge about vaginal birth at term. The guideline focuses on definitions of the physiological stages of labor as well as differentiating between various pathological developments and conditions. It also assesses the need for intervention and the options to avoid interventions. This first part presents recommendations and statements about patient information and counselling, general patient care, monitoring of patients, pain management and quality control measures for vaginal birth. Methods The German recommendations largely reproduce the recommendations of the National Institute for Health and Care Excellence (NICE) CG 190 guideline "Intrapartum care for healthy women and babies". Other international guidelines were also consulted in specific cases when compiling this guideline. In addition, a systematic search and analysis of the literature was carried out using PICO questions, if this was considered necessary, and other systematic reviews and individual studies were taken into account. For easier comprehension, the assessment tools of the Scottish Intercollegiate Guidelines Network (SIGN) were used to evaluate the quality of the additionally consulted studies. Otherwise, the GRADE system was used for the NICE guideline and the evidence reports of the IQWiG were used to evaluate the quality of the evidence. Recommendations Recommendations and statements were formulated based on identified evidence and/or a structured consensus.

Abstract
Traditional preparatory fasting policy prior to iodinated contrast media (ICM) assisted contrast-enhanced CT (CECT) examinations lacks methodologically acceptable evidence. Considering the possible negative effects of preprocedural fasting, the latest European Society of Urogenital Radiology guidelines V10.0 and American Committee of Radiology 2021 guidelines clearly state that preprocedural fasting is not recommended prior to routine intravenous ICM administration. This comprehensive and detailed Review presents the current global dietary preparation policies, potential harm of excessive fasting, and a systematical and well-bedded description of practice advancements of dietary preparation. The evidences revealed that there has been no single instance of vomiting-associated aspiration pneumonia due to the undemanding implementation of preparatory fasting prior to CECT yet. Non-fasting would not increase the incidence of emetic symptoms and the risk of aspiration pneumonia. Not every patient should undergo all CECT examinations without preparatory fasting. There is still much more refinement to be done on the preparatory fasting policy. Changes in traditional preparatory fasting policy will make positive and significant implications on clinical practice. This Review aims to provide operational guidance and suggestions for practitioners and policymakers, motivate efficient, reasonable, safe and normative ICM usage, and achieve optimal patient clinical benefits and high-quality radiological care practices.

The effects of labor on airway outcomes with Supreme™ laryngeal mask in women undergoing cesarean delivery under general anesthesia: a cohort study. BMC Anesthesiol 2020; 20:213. [PMID: 32847548 PMCID: PMC7449044 DOI: 10.1186/s12871-020-01132-5] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/13/2020] [Accepted: 08/20/2020] [Indexed: 11/24/2022] Open
Abstract
BACKGROUND Pregnancy is associated with higher incidence of failed endotracheal intubation and is exacerbated by labor. However, the influence of labor on airway outcomes with laryngeal mask airway (LMA) for cesarean delivery is unknown. METHODS This is a secondary analysis of a prospective cohort study on LMA use during cesarean delivery. Healthy parturients who fasted > 4 h undergoing Category 2 or 3 cesarean delivery with Supreme™ LMA (sLMA) under general anesthesia were included. We excluded parturients with BMI > 35 kg/m2, gastroesophageal reflux disease, or potentially difficult airway (Mallampati score of 4, upper respiratory tract or neck pathology). Anesthesia and airway management reflected clinical standard at the study center. After rapid sequence induction and cricoid pressure, sLMA was inserted as per manufacturer's recommendations. Our primary outcome was time to effective ventilation (time from when sLMA was picked up until appearance of end-tidal carbon dioxide capnography), and secondary outcomes include first-attempt insertion failure, oxygen saturation, ventilation parameters, mucosal trauma, pulmonary aspiration, and Apgar scores. Differences between labor status were tested using Student's t-test, Mann-Whitney U test, or Fisher's exact test, as appropriate. Quantitative associations between labor status and outcomes were determined using univariate logistic regression analysis. RESULTS Data from 584 parturients were analyzed, with 37.8% in labor. Labor did not significantly affect time to effective ventilation (mean (SD) for labor: 16.0 (5.75) seconds; no labor: 15.3 (3.35); mean difference: -0.65 (95%CI: - 1.49 to 0.18); p = 0.1262). However, labor was associated with increased first-attempt insertion failure and blood on sLMA surface. No reduction in oxygen saturation or pulmonary aspiration was noted. CONCLUSIONS Although no significant increase in time to effective ventilation was noted, labor may increase the number of insertion attempts and oropharyngeal trauma with sLMA use for cesarean delivery in parturients at low risk of difficult airway. Future studies should investigate the effects of labor on LMA use in high risk parturients. TRIAL REGISTRATION The study was prospectively registered at clinicaltrials.gov ( NCT02026882 ) on 3 January 2014.

Abstract
There is a lack of consensus in the international scientific community with respect to the most suitable hydration strategies when attending nulliparous women during low-risk births. This paper describes the protocol for a randomized controlled trial to compare two hydration strategies and their influence on maternal and neonatal morbidity. The study population consists of nulliparous women admitted to the obstetrics department of a University Hospital. The women are being randomized into two groups: the "optimal hydration" group, which will be guaranteed 300 ml/hr liquids (crystalloids and bottled mineral water) with a minimum diuresis of 35 ml/hr; and the "variability in hydration" group, which will receive intravenous (alternating normal saline, Ringer's lactate solution, glucose, or Voluven®) and clear (bottled mineral water or isotonic drinks [Aquarius®]) liquids, without any established perfusion rate, and without established minimum diuresis. Outcomes for mothers include duration of labor, cesarean section, fever, and dehydration. Outcomes for newborns are respiratory distress, hypoglycemia, hyponatremia, jaundice, weight loss over 48 hr, and breastfeeding difficulties. Analysis will be per-protocol. Administering optimal hydration may improve health and safety for mothers and their newborn and reduce maternal and neonatal morbidity. The study is registered at www.clinicaltrials.gov. The project received funding by the Ministry of Health of Spain and is approved by the Research Ethics Committee.

Abstract
PURPOSE To compare the effects of two different regimens of intravenous hydration and oral hydration on the duration of active labor. METHODS Two hundred and ninety-three low risk term primigravida in active labor were randomized into three groups. The first group had 99 patients who received oral fluids only, the second group of 98 patients received intravenous Ringer lactate at the rate of 125 ml/h (IV 125 ml) and the third group had 96 patients who received intravenous Ringer lactate at a rate of 250 ml/h (IV 250 ml). Amniotomy and oxytocin administration were allowed according to the physician's discretion. RESULTS The mean duration of labor in the oral fluid group was 391, 363 min in the 125 ml/h group and 343 min in the 250 ml/h group, P = 0.203. The incidence of prolonged labor more than 12 h in the oral fluid group was 7.1% in the oral fluid group, 4.1% in the 125 ml/h group and 3.1% in the 250 ml/h group, P = 0.402. The oxytocin requirement was 37% in the oral group, 32% in the 125 ml/h group and 33% in the 250 ml/h group, P = 0.68. There was a statistically significant reduction in the incidence of vomiting in patients receiving intravenous hydration, i.e. 24.2% in the oral group, 11.2% in the 125 ml/h group and 6.3% in the 250 ml/h group, P = 0.001. There was no difference in the mode of delivery, maternal or neonatal complications between the three groups. CONCLUSION This study establishes a trend towards decreased incidence of prolonged labor and less vomiting in patients receiving intravenous hydration.

Abstract
BACKGROUND AND PURPOSE In order to prevent unexpected events such as aspiration pneumonia, cerebral angiography has been performed under fasting in most cases. We investigated prospectively the necessity of fasting before elective cerebral angiography. MATERIALS AND METHODS The study is an open-labeled clinical trial without random allocation. In total, 2554 patients who underwent elective cerebral angiography were evaluated on development of nausea, vomiting, and pulmonary aspiration during and after angiography. Potential risks and benefits associated with fasting were provided in written documents and through personal counseling to patients before the procedure. The patients chose their fasting or nonfasting option. No restriction in diet was given after angiography. The patients were observed for 24 hours. Nausea and vomiting during and within 1 hour after angiography was considered as a positive event associated with cerebral angiography. RESULTS The overall incidence of nausea and vomiting during and within 1 hour after angiography was 1.05% (27/2554 patients). There was no patient with pulmonary aspiration. No statistical difference in nausea and vomiting development between the fasting and the diet groups was found. CONCLUSIONS The incidence of nausea and vomiting associated with cerebral angiography is low and not affected by diet or fasting. Pulmonary aspiration had no difference between the diet and the fasting group. Our study suggests that fasting may not be necessary for patients who undergo elective cerebral angiography.

Abstract
The critically ill pregnant patient poses a unique challenge to the clinician, requiring a thorough understanding of normal and abnormal maternal and fetal physiology associated with pregnancy. The morbidly obese patient presents even greater challenges to the clinician, and morbidity and mortality are proportionately increased. Because increased numbers of obese pregnant women are now admitted to intensive care units, practitioners must be aware of the physiology associated with both pregnancy and obesity. A multidisciplinary approach is imperative to prevent both maternal and fetal morbidity and mortality for these very complex patients, especially when they are admitted to the ICU with critical illness.

Abstract
Rapid sequence induction is currently the recommended technique in general anaesthesia for caesarean section. However, the usefulness of the ProSeal laryngeal mask airway as a rescue airway in the event of difficult or failed intubation has been recognised in numerous case reports. In this study, we report the experience of the use of the ProSeal laryngeal mask in 3000 elective caesarean sections in a single centre, using a method of insertion that allows a rapid establishment of a patent airway together with gastric drainage.

Abstract
OBJECTIVE To investigate the effect of feeding during labour on obstetric and neonatal outcomes. DESIGN Prospective randomised controlled trial. SETTING Birth centre in London teaching hospital. PARTICIPANTS 2426 nulliparous, non-diabetic women at term, with a singleton cephalic presenting fetus and in labour with a cervical dilatation of less than 6 cm. INTERVENTION Consumption of a light diet or water during labour. MAIN OUTCOME MEASURES The primary outcome measure was spontaneous vaginal delivery rate. Other outcomes measured included duration of labour, need for augmentation of labour, instrumental and caesarean delivery rates, incidence of vomiting, and neonatal outcome. RESULTS The spontaneous vaginal delivery rate was the same in both groups (44%; relative risk 0.99, 95% confidence interval 0.90 to 1.08). No clinically important differences were found in the duration of labour (geometric mean: eating, 597 min v water, 612 min; ratio of geometric means 0.98, 95% confidence interval 0.93 to 1.03), the caesarean delivery rate (30% v 30%; relative risk 0.99, 0.87 to 1.12), or the incidence of vomiting (35% v 34%; relative risk 1.05, 0.9 to 1.2). Neonatal outcomes were also similar. CONCLUSIONS Consumption of a light diet during labour did not influence obstetric or neonatal outcomes in participants, nor did it increase the incidence of vomiting. Women who are allowed to eat in labour have similar lengths of labour and operative delivery rates to those allowed water only. TRIAL REGISTRATION Current Controlled Trials ISRCTN33298015.

Abstract
The prevalence of obesity continues to increase despite preventive strategies. Obese parturients are at increased risk of having either concurrent medical problems or superimposed antenatal diseases such as pre-eclampsia and gestational diabetes. Moreover, they have a tendency to labour abnormally contributing to increased instrumental delivery and Caesarean section. Obesity is a risk factor for anaesthesia related maternal mortality. Morbidly obese women must be considered as high-risk and deserve an anaesthetic consultation during their antenatal care. The significant difficulty in administering epidural analgesia should not preclude their use in labour. A more liberalised use of regional techniques may be a means to further reduce anaesthesia-related maternal mortality in the obese population. The mother's life should not be jeopardised to save a compromised fetus. Prophylactic placement of an epidural catheter when not contraindicated in labouring morbidly obese women would potentially decrease anaesthetic and perinatal complications associated with attempts at emergency provision of regional or general anaesthesia. Early mobilisation, aggressive chest physiotherapy and adequate pain control are essential components of effective postoperative care.

Abstract
OBJECTIVES To provide a current review of the literature regarding airway problems in pregnancy and management. BACKGROUND Obstetrical anesthesia is considered to be a high-risk practice that exposes the anesthesiologist to increased medicolegal liability. Anesthetic management of a parturient is a challenge because it involves simultaneous care of both mother and baby. Failure to appropriately manage a difficult or failed intubation increases the risk of hypoxemic cardiopulmonary arrest and/or pulmonary aspiration, resulting in a high probability of maternal morbidity and mortality. DATA Anesthesia is the seventh leading cause of maternal mortality in the United States. Anatomic and physiologic changes during pregnancy place the parturient at increased risk for airway management problems. It is essential to perform a thorough preanesthetic evaluation and identify the factors predictive of difficult intubation. Airway devices such as the laryngeal mask airway, ProSeal, intubating laryngeal mask airway, Combitube, and laryngeal tube are described and have been used during failed intubation in pregnant patients. CONCLUSION Teamwork between an anesthesiologist and an obstetrician is absolutely essential for the safety of both the mother and baby. Most of us tend to agree that airway emergencies have a way of occurring at the worst possible times. It is essential that all anesthesia care practitioners must have a preconceived and well thought-out algorithm and emergency airway equipment to deal with airway emergencies during difficult or failed intubation of a parturient.

Abstract
Obstetric anesthesia is considered to be a difficult, high-risk practice that exposes the anesthesiologist to increased medicolegal liability. Anesthetic management of parturient patients is a challenge, as it involves simultaneous care of two lives. The anesthesia practitioner has a duty to provide safe anesthetic care, including effective airway management when providing regional or general anesthesia. The potential need to manipulate the airway is perhaps the leading cause of concern among obstetric anesthesiologists.
