Postpartum Complications

Postpartum complications are a broad range of physical and psychological complications that can arise during the postpartum period.

They include postpartum haemorrhage, postpartum infection (including endometritis and wound infection), venous thromboembolism, and the spectrum of postpartum mental health conditions.

The mental health conditions range from the common, mild, self-limiting "baby blues" to postpartum depression and, rarely, postpartum psychosis. Postpartum psychosis is a genuine psychiatric emergency.

Full, structured postpartum surveillance is essential for prompt recognition and timely management of this diverse range of complications.

Classification of postpartum mental health conditions

• "Baby blues" is the mildest and by far the commonest postpartum mood disturbance. It affects a substantial majority of postpartum women to some degree.
• It is characterised by transient emotional lability, tearfulness, anxiety and irritability. It typically peaks around the third to fifth postpartum day and resolves spontaneously within approximately two weeks without specific treatment.
• It is a normal, expected physiological and psychological adjustment reaction rather than a pathological condition. It needs no intervention beyond reassurance and support.
• Postpartum depression is a more significant, persistent depressive episode developing within the postpartum period, conventionally within the first year after delivery. It is managed under the broader principles of depressive disorders, with specific relevance to this timeframe and context.
• It warrants the same full diagnostic and treatment approach as major depressive disorder in any other context. Additional considerations are breastfeeding compatibility of any pharmacological treatment and the psychosocial context of new parenthood.
• Postpartum psychosis is a rare but genuine psychiatric emergency. It has acute onset, typically within the first two weeks postpartum. Symptoms are psychotic: delusions, hallucinations and severe, rapidly fluctuating mood disturbance.
• It carries a substantial, serious risk to both maternal and infant safety. It requires immediate, urgent psychiatric assessment and, generally, inpatient psychiatric admission.

• Postpartum endometritis presents with fever, uterine tenderness, and abnormal, often malodorous lochia. It typically develops within the first several days after delivery.
• Risk is substantially elevated after caesarean delivery compared with vaginal delivery. It is further elevated by prolonged labour, prolonged rupture of membranes, and multiple vaginal examinations during labour.
• Wound infection may affect a caesarean incision or a perineal repair after vaginal delivery. It presents with localised erythema, warmth and tenderness. In more significant infection there is purulent discharge or wound breakdown, and in more severe cases systemic features of infection.
• Postpartum venous thromboembolism presents with the standard clinical features of deep vein thrombosis or pulmonary embolism. The postpartum period, particularly the first several weeks, carries substantially elevated thromboembolic risk.
• This reflects the combined effect of the pregnancy hypercoagulable state persisting into the early postpartum period, reduced mobility and, where relevant, the additional risk of caesarean delivery.
• Postpartum depression presents with the standard features of major depressive disorder within the postpartum timeframe. Particular attention is needed to distinguish it from normal, expected new-parent fatigue and adjustment. Accurate identification is directly relevant to timely treatment.
• Postpartum psychosis presents acutely and dramatically, with rapidly fluctuating mood, confusion and delusions. Delusions frequently relate to the infant: beliefs about the infant's identity or wellbeing, or the mother's own capacity or right to care for the infant. Some cases have hallucinations.
• It is a rapidly evolving, high-risk presentation requiring immediate recognition and urgent psychiatric intervention.

• Diagnosis of postpartum endometritis and wound infection is clinical, based on the characteristic features. Blood cultures and, where relevant, wound or vaginal swab culture support identification of the causative organism and guide targeted antibiotic therapy.
• Diagnosis of postpartum venous thromboembolism follows the standard diagnostic principles, adapted for the physiological and practical context of the postpartum period.
• Structured, proactive screening for postpartum depression uses validated tools, including the Edinburgh Postnatal Depression Scale, at routine postpartum contact points. This supports systematic identification of a common, frequently underrecognised condition.
• Postpartum psychosis is diagnosed through urgent, full psychiatric assessment. The acute, dramatic presentation and rapid symptom evolution generally support relatively prompt recognition once suspicion is raised.
• Initial presentation can occasionally be subtle or atypical. Keep a low threshold for urgent psychiatric referral where any concerning feature is present in the early postpartum period.

• Postpartum endometritis is managed with broad-spectrum intravenous antibiotic therapy. It covers the polymicrobial organism profile typically involved. Treatment continues until clinical improvement is achieved and the woman remains afebrile for a defined period. Broadly similar general principles apply as for intra-amniotic infection.
• Wound infection is managed according to severity. Milder infection is treated with oral antibiotics. More significant infection or wound breakdown needs surgical wound exploration and drainage, with intravenous antibiotic therapy.
• Postpartum venous thromboembolism is managed following the standard therapeutic anticoagulation principles. Pay careful attention to breastfeeding compatibility when selecting the anticoagulant.
• "Baby blues" requires no specific treatment beyond reassurance, support and clear information on the expected, self-limiting natural history.
• Persistence beyond approximately two weeks, or severity disproportionate to the typically mild presentation, warrants further evaluation for postpartum depression.
• Postpartum depression is managed following the standard principles of depressive disorder management. This incorporates psychological therapy and, where indicated, pharmacological treatment. Where the woman is breastfeeding and wishes to continue, select an antidepressant carefully, with a favourable breastfeeding safety profile. Provide full practical and social support addressing the context of new parenthood.
• Postpartum psychosis requires immediate, urgent psychiatric assessment. In the great majority of cases it needs inpatient psychiatric admission, ideally to a specialist mother and baby unit where available. This supports continued mother-infant contact and bonding in a safe, supervised setting.
• Standard treatment is antipsychotic medication. In some cases mood stabilising treatment or electroconvulsive therapy is used for severe, treatment-refractory presentations. Maintain careful, ongoing attention to maternal and infant safety throughout acute treatment.
• Full, structured, proactive postpartum surveillance across this range of physical and psychological complications underpins safe postpartum care. Give women and their families clear, accessible information on warning symptoms and how to access prompt assessment and support.
