A survey in the West Midlands of the United Kingdom of current practice in managing hypotension in lower segment caesarean section under spinal anaesthesia

BACKGROUND

Spinal anaesthesia, the most common form of anaesthesia for caesarean section, leads to sympathetic blockade and profound maternal hypotension resulting in adverse maternal and neonatal outcomes. Hypotension, nausea and vomiting remain common but until the publication of the National Institute of Health and Care Excellence (NICE) 2021 guidance, no national guideline existed on how best to manage maternal hypotension following spinal anaesthesia for caesarean section. A 2017 international consensus statement recommended prophylactic vasopressor administration to maintain a systolic blood pressure of >90% of an accurate pre-spinal value, and to avoid a drop to <80% of this value. This survey aimed to assess regional adherence to these recommendations, the presence of local guidelines for management of hypotension during caesarean section under spinal anaesthesia, and the individual clinician's treatment thresholds for maternal hypotension and tachycardia.

METHODS

The West Midlands Trainee-led Research in Anaesthesia and Intensive Care Network co-ordinated surveys of obstetric anaesthetic departments and consultant obstetric anaesthetists across 11 National Health Service Trusts in the Midlands, England.

RESULTS

One-hundred-and-two consultant obstetric anaesthetists returned the survey and 73% of sites had a policy for vasopressor use; 91% used phenylephrine as the first-line drug but a wide range of recommended delivery methods was noted and target blood pressure was only listed in 50% of policies. Significant variation existed in both vasopressor delivery methods and target blood pressures.

CONCLUSIONS

Although NICE has since recommended prophylactic phenylephrine infusion and a target blood pressure, the previous international consensus statement was not adhered to routinely.

Sertraline-induced hypomania: a genuine side-effect

OBJECTIVE

Antidepressants including selective serotonin reuptake inhibitor (SSRI)-associated mania or hypomania has been well documented in the literature but these patients with switch have either mood disorders or various risk factors for bipolar disorder. This case report examines SSRI-induced hypomania in a patient with dissociative disorder and highlights hypomania as a genuine side-effect of sertraline rather than a switch.

METHOD

A 23-year-old female patient with dissociative disorder has been described.

RESULTS

Hypomanic symptoms emerged during treatment with sertraline at the dose of 50 mg/day after 3-4 days of initiation of therapy and had complete recovery within 7 days after stopping sertraline.

CONCLUSION

In the absence of risk factors for manic switch, sertraline-induced hypomania may be a true side-effect of drug.
