Patient-controlled epidural analgesia in labour—Is a continuous infusion of benefit? Labor and delivery units should have personnel and equipment readily available to manage airway emergencies consistent with the ASA Practice Guidelines for Management of the Difficult Airway‡‡‡ to include a pulse oximeter and carbon dioxide detector. This article is featured in “This Month in Anesthesiology,” page 1A. Meta-analysis of RCTs indicate that the use of pencil-point spinal needles reduces the frequency of postdural puncture headache when compared with cutting-bevel spinal needles (Category A1-B evidence).85–89. Satisfaction, control and pain relief: Short- and long-term assessments in a randomised controlled trial of low-dose and traditional epidurals and a non-epidural comparison group. Why does the statement differ from existing guidelines? This document represents the first practice guideline to be developed as a collaborative effort between the ASA and a subspecialty society (Society for Obstetric Anesthesia and Perinatology) with content expertise relevant to the recommendations. The lack of sufficient scientific evidence in the literature may occur when the evidence is either unavailable (i.e., no pertinent studies found) or inadequate. In 2014, the ASA Committee on Standards and Practice Parameters requested that the updated guidelines published in 2007 be reevaluated. Practice Guidelines for Preoperative Fasting and the Use of Pharmacologic Agents to Reduce the Risk of Pulmonary Aspiration: Application to Healthy Patients Undergoing Elective Procedures An Updated Report by the American Society of Anesthesiologists Task Force on Preoperative Fasting and the Use of Pharmacologic Diabetes â Fasting BMP; ECG for all patients with evidence of end organ damage or compromised exercise Results of the surveys are reported in tables 5 and 6, and in the text of the guidelines. The consultants and ASA members strongly agree that (1) the patient undergoing elective surgery (e.g., scheduled cesarean delivery or postpartum tubal ligation) should undergo a fasting period for solids of 6 to 8 h depending on the type of food ingested (e.g., fat content); (2) laboring patients with additional risk factors for aspiration (e.g., morbid obesity, diabetes mellitus, and difficult airway) or patients at increased risk for operative delivery (e.g., nonreassuring fetal heart rate pattern) may have further restrictions of oral intake, determined on a case-by-case basis; and (3) solid foods should be avoided in laboring patients. An IV infusion should be established before the initiation of neuraxial analgesia or general anesthesia and maintained throughout the duration of the neuraxial analgesic or anesthetic. Vaginal birth after cesarean section: Results of a multicenter study. Maternal and fetal haemodynamic effects of spinal and extradural anaesthesia for elective caesarean section. Combined spinal–epidural techniques may be used to provide effective and rapid onset of analgesia for labor. Randomized controlled trials report comparative findings between clinical interventions for specified outcomes. Combined low-dose spinal-epidural anesthesia. Titrate sedation/analgesia carefully due to the potential risks of respiratory depression and pulmonary aspiration during the immediate postpartum period. If an epidural catheter is in place and the patient is hemodynamically stable, consider providing epidural anesthesia. Techniques for removal of retained placenta include (1) anesthetic techniques for removal of retained placenta and (2) nitroglycerin for uterine relaxation. Hypertensive disorders and pregnancy-related stroke: Frequency, trends, risk factors, and outcomes. Extradural analgesia in labour: Complications of three techniques of administration. The guidelines do not apply to patients undergoing surgery during pregnancy, gynecological patients, or parturients with chronic medical disease (e.g., severe cardiac, renal, or neurological disease). Evidence was obtained from two principal sources: scientific evidence and opinion-based evidence. 1 0 obj
The effect of epidural opioids on maternal oxygenation during labour and delivery. This statement presents new findings from the scientific literature since 2006 and surveys of both expert consultants and randomly selected ASA members.

If cardiac arrest occurs, initiate standard resuscitative measures. When tracheal intubation has failed, consider ventilation with mask and cricoid pressure or with a supraglottic airway device (e.g., laryngeal mask airway, intubating laryngeal mask airway, and laryngeal tube) for maintaining an airway and ventilating the lungs. Naan DerThaal. If labor duration is anticipated to be longer than the analgesic effects of the spinal drugs chosen, or if there is a reasonable possibility of operative delivery, then consider a catheter technique instead of a single-injection technique. Prophylactic ephedrine and hypotension associated with spinal anesthesia for cesarean delivery. The consultants and ASA members strongly agree that labor and delivery units should have personnel and equipment readily available to manage airway emergencies consistent with the ASA Practice Guidelines for Management of the Difficult Airway, to include a pulse oximeter and carbon dioxide detector. If it is not possible to ventilate or awaken the patient, a surgical airway should be performed. Use of LMA for awake intubation for caesarean section. The consultants and ASA members strongly agree that (1) the decision to use a particular anesthetic technique for cesarean delivery should be individualized, based on anesthetic, obstetric, or fetal risk factors (e.g., elective vs. emergency), the preferences of the patient, and the judgment of the anesthesiologist; (2) uterine displacement (usually left displacement) should be maintained until delivery regardless of the anesthetic technique used; (3) consider selecting neuraxial techniques in preference to GA for most cesarean deliveries; (4) if spinal anesthesia is chosen, use pencil-point spinal needles instead of cutting-bevel spinal needles; (5) for urgent cesarean delivery, an indwelling epidural catheter may be used as an alternative to initiation of spinal anesthesia; and (6) GA may be the most appropriate choice in some circumstances (e.g., profound fetal bradycardia, ruptured uterus, severe hemorrhage, severe placental abruption, umbilical cord prolapse, and preterm footling breech). Anesthesiology 2013; 118:251–70. This teaching predominately comes from the ASAâs Practice Guideline for Sedation and Analgesia by Non-Anesthesiologists published in 2002 (and earlier iterations). When a neuraxial technique is chosen, appropriate resources for the treatment of complications (e.g., hypotension, systemic toxicity, and high spinal anesthesia) should be available. The literature is insufficient to assess whether, when caring for the complicated parturient, the early insertion of a neuraxial catheter, with immediate or later administration of analgesia, improves maternal or neonatal outcomes. * American Society of Anesthesiologists: Practice guidelines for pre-operative fasting and the use of ⦠ASA Admits NPO Guidelines are Entirely Arbitrary. Case reports suggest that the availability of equipment for the management of airway emergencies may be associated with reduced maternal, fetal, and neonatal complications (Category B4-B evidence).220–228. Unless otherwise specified, outcomes for the listed interventions refer to the reduction of maternal, fetal, and neonatal complications. A complete bibliography used to develop these guidelines, organized by section, is available as Supplemental Digital Content 2, http://links.lww.com/ALN/B220. Comparison of intramuscular and epidural administration of four dose regimens. Acute hypotension associated with intraoperative cell salvage using a leukocyte depletion filter during management of obstetric hemorrhage due to amniotic fluid embolism. In these cases, the insertion of a neuraxial catheter may precede the onset of labor or a patient’s request for labor analgesia. ACOG Practice Bulletin. Labor and delivery units should have personnel and equipment readily available to manage airway emergencies consistent with the ASA Practice Guidelines for Management of the Difficult Airway,‡‡‡ to include a pulse oximeter and carbon dioxide detector. Patient-controlled epidural analgesia in obstetric anaesthetic practice. First, original published research studies from peer-reviewed journals published subsequent to the previous update were reviewed. The ASA members agree and the consultants strongly agree that (1) oral intake of moderate amounts of clear liquids may be allowed for uncomplicated laboring patients and (2) the uncomplicated patient undergoing elective surgery (e.g., scheduled cesarean delivery or postpartum tubal ligation) may have moderate amounts of clear liquids up to 2 h before induction of anesthesia. The choice of a specific neuraxial technique should be individualized and based on anesthetic risk factors, obstetric risk factors, patient preferences, progress of labor, and resources at the facility. Severe thrombocytopenia, type 2B von Willebrand disease and pregnancy. An observational study reported that platelet count and fibrinogen values are associated with the frequency of postpartum hemorrhage (Category B2 evidence).15 Other observational studies and case reports suggest that a platelet count may be useful for diagnosing hypertensive disorders of pregnancy, such as preeclampsia; hemolysis, elevated liver enzymes, and low platelet count syndrome; and other conditions associated with coagulopathy (Category B3/B4-B evidence).16–23. Anesthetic care for cesarean delivery consists of (1) equipment, facilities, and support personnel; (2) general, epidural, spinal, or CSE anesthesia; (3) IV fluid preloading or coloading; (4) ephedrine or phenylephrine; and (5) neuraxial opioids for postoperative analgesia after neuraxial anesthesia. Supplemental Digital Content is available in the text. To be accepted as significant findings, Mantel–Haenszel odds ratios must agree with combined test results whenever both types of data are assessed. Delayed amniotic fluid embolism following caesarean section under spinal anaesthesia. Survey responses from Task Force–appointed expert consultants are reported in summary form in the text, with a complete listing of the consultant survey responses reported in appendix 2. Continuous epidural infusion may be used for effective analgesia for labor and delivery. Institutions providing obstetric care should have resources available to manage hemorrhagic emergencies (table 1). The effect of colloid co-hydration on the use of phenylephrine and hemodynamics during low-dose combined spinal-epidural anesthesia for cesarean delivery. This should include, but is not limited to, a maternal health and anesthetic history, a relevant obstetric history, a baseline blood pressure measurement, and an airway, heart, and lung examination, consistent with the American Society of Anesthesiologists (ASA) “Practice Advisory for Preanesthesia Evaluation.”‖. A preformulated strategy for intubation of the difficult airway should be in place. ASA Practice Guidelines for Preoperative Fasting By Thelma Z. Korpman, M.D., MBA I have been in the practice of anesthesia for over 30 years and have rewritten NPO guidelines for my institution at least once for every year in practice. A dose-response study of prophylactic intravenous ephedrine for the prevention of hypotension during spinal anesthesia for cesarean delivery. The antiemetic efficacy and safety of prophylactic metoclopramide for elective cesarean delivery during spinal anesthesia. PRACTICE guidelines are systematically developed recommendations that assist the practitioner and patient in making decisions about health care. Comparison of the maternal and neonatal effects of epidural block and of combined spinal-epidural block for cesarean section. Prophylactic ephedrine preceding spinal analgesia for cesarean section. For urgent cesarean delivery, an indwelling epidural catheter may be used as an alternative to initiation of spinal or general anesthesia. The effect of magnesium trisilicate mixture, metoclopramide and ranitidine on gastric pH, volume and serum gastrin. The patient should undergo a fasting period of solids for 6 â8 hours, depending on the type of food ingested (e.g., fat content). These Practice Guidelines update the âPractice Guidelines for Obstetric Anesthesia: An Updated Report by the American Society of Anesthesiologists Task Force on Obstetric Anesthesia,â adopted by the American Society of Anesthesiologists (ASA) in 2006 and published in 2007. Under exceptional circumstances, these standards may be modified. 4 0 obj
The ASA members agree and the consultants strongly agree that (1) a routine blood cross-match is not necessary for healthy and uncomplicated parturients for vaginal or operative delivery and (2) the decision whether to order or require a blood type and screen or cross-match should be based on maternal history, anticipated hemorrhagic complications (e.g., placenta accreta in a patient with placenta previa and previous uterine surgery), and local institutional policies. Despite these guidelines⦠Circulation 2010; 122 (18 suppl 3):S640–933. Meta-analysis of RCTs report reduced analgesic consumption (Category A1-B evidence) when PCEA is compared with CIE.102–107 Meta-analysis of RCTs report equivocal findings for duration of labor, mode of delivery, motor block, and 1- and 5-min Apgar scores when PCEA is compared with CIE (Category A1-E evidence).103–116 Meta-analysis of RCTs indicate greater analgesic efficacy for PCEA with a background infusion compared with PCEA without a background infusion (Category A1-B evidence)117–121 and is equivocal regarding mode of delivery and frequency of motor block (Category A1-E evidence).117–122. Nulliparous active labor, epidural analgesia, and cesarean delivery for dystocia. Fetal and maternal effects of phenylephrine and ephedrine during spinal anesthesia for cesarean delivery. The Task Force recognizes that in laboring patients the timing of delivery is uncertain; therefore, adherence to a predetermined fasting period before nonelective surgical procedures is not always possible. The updated searches covered an 11-yr period from January 1, 2005 to July 31, 2015. Approved by the ASA House of Delegates on October 28, 2015. The consultants and ASA members strongly agree that fetal heart rate patterns should be monitored by a qualified individual before and after administration of neuraxial analgesia for labor. Each pertinent outcome reported in a study was classified by evidence category and level, and designated as either beneficial, harmful, or equivocal.
