Rationale:Spinal epidural abscess is an uncommon complication in clinical practice. If the abscess is large enough, the patient will rapidly develop neurologic signs of spinal injury, and urgent neurosurgical intervention may be required.Patient concerns:Rapid and correct diagnosis and treatment is important for spinal epidural abscess complication.Diagnoses:This report describes a cervical epidural abscess (CEA) caused by epidural analgesia, wherein the patient was punctured twice. A CEA was suspected based on the patient's significant neck pain and elevated white blood cell and neutrophil counts. A CEA from C6 to T8 was confirmed by magnetic resonance imaging scan.Interventions:The patient was treated with a combination of intravenous vancomycin and imipenem/cilastatin for more than 4 weeks.Outcomes:After more than 2 weeks of intensive antibiotic treatment, the epidural abscess gradually diminished in size, the white blood cell count, neutrophil count, hyperallergic C-reactive protein (CRP), and general CRP decreased, and the patient's neck and back pain resolved. After more than 4 weeks of anti-inflammation therapy, the epidural abscess was completely absorbed, and there was no relapse during the 3-month follow-up period.Lessons:Although an effective combination of intravenous antibiotics can cure an epidural abscess, caution is warranted when performing epidural steroid injections in immunocompromised patients.

Background Compared with singleton pregnancy, twin gestation is featured by a greater increase in cardiac output. Therefore, norepinephrine might be more suitable than phenylephrine for maintaining blood pressure during cesarean section for twins, as phenylephrine causes reflex bradycardia and a resultant decrease in cardiac output. This study was to determine whether norepinephrine was superior to phenylephrine in maintaining maternal hemodynamics during cesarean section for twins. Methods Informed consent was obtained from all the patients before enrollment. In this double-blinded, randomized clinical trial, 100 parturients with twin gestation undergoing cesarean section with spinal anesthesia were randomized to receive prophylactic norepinephrine (3.2 μg/min) or phenylephrine infusion (40 μg/min). The primary outcome was the change of heart rate and blood pressure during the study period. The secondary outcomes were to compare maternal complications, neonatal outcomes, Apgar scores and umbilical blood acid-base status between the two vasopressors. Results There was no significant difference observed for the change of heart rate between two vasopressors. The mean standardized area under the curve of heart rate was 78 ± 12 with norepinephrine vs. 74 ± 11 beats/min with phenylephrine (mean difference 4.4, 95%CI − 0.1 to 9.0; P = .0567). The mean standardized area under the curve of systolic blood pressure (SBP) was significantly lower in parturients with norepinephrine, as the mean of differences in standardized AUC of SBP was 6 mmHg, with a 95% CI from 2 to 9 mmHg (P = .0013). However, requirements of physician interventions for correcting maternal hemodynamical abnormalities (temporary cessation of vasopressor infusion for reactive hypertension, rescuing vasopressor bolus for hypotension and atropine for heart rate less < 50 beats/min) and neonatal outcomes were also not significantly different between two vasopressors. Conclusion Infusion of norepinephrine was not associated with less overall decrease in heart rate during cesarean section for twins, compared with phenylephrine.
