Cholera in Pregnancy (Second or Third Trimester) When Initial Oral Rehydration Management Is No Longer Sufficient
Clinical Scenario
This protocol applies to a pregnant patient in the second or third trimester with cholera whose condition has escalated beyond what the initial management line could contain — specifically when blood pressure has fallen or severe dehydration has supervened.
Pregnancy — second or third trimester
Why Pregnancy Shapes This Protocol
Patients with coexisting conditions, including pregnancy, require a dedicated evaluation pathway regardless of the initial degree of dehydration. The second and third trimester presentation is assessed according to a specific clinical table.
When the Previous Step Was Not Enough
The prior management line targets pregnant patients with some or no dehydration and a systolic blood pressure above 90 mmHg, using oral rehydration and observation alongside single-dose antibiotic therapy. Its goals are to maintain systolic blood pressure above 90 mmHg and prevent progression to severe dehydration. This protocol is indicated when those goals are not met — when SBP drops to 90 mmHg or below, or when severe dehydration develops.
Management Approach (Overview Only)
Once this threshold is crossed, immediate intravenous fluid resuscitation becomes the primary intervention, with the type and sequence determined by the haemodynamic response at defined reassessment points. Oral rehydration is continued alongside where the patient can tolerate it, and a single-dose antibiotic regimen is part of the overall approach. The complete stepwise algorithm — including specific fluids, escalation criteria, and decision rules — is in the full protocol.
Treatment Goals
Systolic blood pressure rising above 90 mmHg, resolution of a weak pulse, and restoration of normal consciousness.

- The second and third trimester initial evaluation is detailed in Table 6.
- Patients with coexisting conditions (including pregnancy) or comorbidities (such as Severe Acute Malnutrition (SAM), and HIV), regardless of the degree of dehydration.
- Bolus of 30 ml/kg of RL over 30 minutes.
- Continue with 70 ml/kg of RL over 2 and a half hours.
- Encourage the patient to take ORS as frequently as possible and at least 250 ml of ORS after each stool.
- Single dose antibiotic therapy within 4 hours or as soon as possible (Refer to table 5 on antibiotics).
- Repeat boluses of 30 ml/kg over 30 minutes until the SBP is > 90 and/or danger signs resolve then, resume the previous infusion of 70 ml/kg.
