Review of a high-risk obstetric anesthesia antepartum consult clinic

Case report: Successful anesthesia management of noncardiac surgery in a patient with single atrium

Background

Single atrium is very rare congenital cardiac anomaly in adults. The prognosis of patients with single atrium is very poor, with 50% of patients dying owing to cardiopulmonary complications in childhood. Herein, we focused on anesthesia management for noncardiac surgery in patients with single atrium.

Case presentation

A 58-year-old male with a history of bilateral varicocele underwent laparotomy for high-position ligation of the spermatic vein. The patient also had a history of single atrium, atrial fibrillation, chronic heart failure, pulmonary hypertension (PH), and complete right bundle branch block (CRBBB). Given the significant complications associated with general anesthesia in patients with PH, we preferred to use low-dose epidural anesthesia for this patient. Transthoracic echocardiography was used to assess cardiac function before and during surgery and guide perioperative fluid therapy. To limit the stress response, we used a regional nerve block for reducing postoperative pain. Furthermore, we used norepinephrine to appropriately increase the systemic vascular resistance in response to the reduction of systemic vascular resistance caused by epidural anesthesia.

Conclusion

Low-dose epidural anesthesia can be safely used in patients with single atrium and PH. The use of perioperative transthoracic echocardiography is helpful in guiding fluid therapy and effectively assessing the cardiac structure and function of patients. Prophylactic administration of norepinephrine before epidural injection may make it easier to maintain the patient's BP.

Remote Obstetric Anesthesia: Leveraging Telemedicine to Improve Fetal and Maternal Outcomes

In the United States, the prevalence of pregnancy-related deaths has risen significantly over the past 20 years. Pregnant women at high risk for peripartum complications should undergo anesthesia consultation before delivery so that a management plan can be created between the obstetrician, anesthesiologist, and patient to ensure optimal outcomes for both the mother and newborn. However, few hospitals outside of major, urban, academic medical centers have dedicated anesthesiologists specially trained in obstetric anesthesia and the resources available to expedite optimization of high-risk parturient comorbidities. Telemedicine is a valuable tool by which evaluation, triaging, and multidisciplinary coordination can be provided for high-risk obstetric patients living in remote or rural communities without access to specialized, maternal care medical facilities. This review examines the existing literature regarding telemedicine use in preoperative anesthesia and antenatal obstetrics and identifies areas for future research. Furthermore, the benefits and potential barriers of implementing a telemedicine program specifically dedicated to obstetric anesthesia are discussed.

Neuraxial analgesia in a parturient with the VACTERL association undergoing labor and vaginal delivery

Introduction

The term VACTERL is an acronym for an association of congenital malformations: including vertebral, anal, cardiac, tracheo-esophageal, renal and limb anomalies. VACTERL anomalies pose a formidable challenge to anesthesiologists. We describe the anesthetic management of a parturient with VACTERL association, who underwent neuraxial analgesia for labor and vaginal delivery.

Case report

A 23 year old primigravida at 39 weeks gestation presented in labor at 4 cm cervical dilatation, completely effaced, requesting labor analgesia. Past medical history included VACTERL association with an imperforate anus and a partial endocardial cushion defect, both repaired in early childhood. She also had significant dorso-lumbar scoliosis with an extra lumbar vertebra. An MRI performed at 14 years age revealed the above findings with no spinal cord abnormalities. With a normal neurologic exam, a combined spinal epidural technique was performed. Despite significant scoliosis, the epidural space was identified at approximately the L3–L4 interspace at a depth of 5 cm. Spinal Fentanyl 25 mcg was administered followed by continuous patient-controlled epidural analgesia. The patient experienced excellent pain relief throughout her labor, and had an uneventful vaginal delivery 5 h after epidural placement.

Discussion

The rarity of VACTERL association in the obstetric population with its extensive anomalies mandates a multidisciplinary approach in the prenatal period as it can pose major challenges to all health care providers, including airway, ventilatory, cardiac and neuraxial problems. This is the first reported case of a successful and safe neuraxial technique in a laboring patient with the VACTERL association with albeit limited vertebral and spinal cord anomalies.

Combined spinal-epidural anesthesia for cesarean delivery in a patient with cor triloculare biventriculare

BACKGROUND

Cor triloculare biventriculare accounts for approximately 0.31% of cases of congenital heart disease (CHD). Moreover, people with cor triloculare biventriculare always have shorter life spans, and cases of gestation are rare. There have been various related reports of cor triloculare biventriculare in recent years.

CASE PRESENTATION

We described an emergency cesarean section of a 30-year-old, 38-weeks-pregnant woman suffering from cardiac insufficiency and fetal distress. Combined spinal-epidural anesthesia was performed safely, and a male baby was smoothly delivered 10 min after the procedure without any adverse outcome on the mother or newborn. After surgery, we advised that the patient submit to an echocardiogram examination, which revealed the congenital heart disease cor triloculare biventriculare.

CONCLUSIONS

Combined spinal-epidural anesthesia was administered to a patient with cor triloculare biventricularethis with good effect, ensuring the patient's safety and meeting the need for emergency surgery.
