Ultrasound scan<br />

Doppler ultrasound<br />

of fetal blood<br />

vessels<br />

B.2.4: One ultrasound scan be<strong>for</strong>e 24 weeks of gestati<strong>on</strong> (early<br />

ultrasound) is recommended <strong>for</strong> pregnant women to estimate<br />

gestati<strong>on</strong>al age, improve detecti<strong>on</strong> of fetal anomalies and multiple<br />

pregnancies, reduce inducti<strong>on</strong> of labour <strong>for</strong> post-term <strong>pregnancy</strong>, and<br />

improve a woman’s <strong>pregnancy</strong> <strong>experience</strong>.<br />

B.2.5: Routine Doppler ultrasound examinati<strong>on</strong> is not recommended <strong>for</strong><br />

pregnant women to improve maternal and perinatal outcomes. v<br />

Recommendati<strong>on</strong><br />

C.1: A seven-day antibiotic regimen is recommended <strong>for</strong> all pregnant<br />

women with asymptomatic bacteriuria (ASB) to prevent persistent<br />

bacteriuria, preterm birth and low birth weight.<br />

C.2: Antibiotic prophylaxis is <strong>on</strong>ly recommended to prevent recurrent<br />

urinary tract infecti<strong>on</strong>s in pregnant women in the c<strong>on</strong>text of rigorous<br />

research.<br />

C.3: Antenatal prophylaxis with anti-D immunoglobulin in n<strong>on</strong>-sensitized<br />

Rh-negative pregnant women at 28 and 34 weeks of gestati<strong>on</strong> to prevent<br />

RhD alloimmunizati<strong>on</strong> is <strong>on</strong>ly recommended in the c<strong>on</strong>text of rigorous<br />

research.<br />

C.4: In endemic areas, w preventive anthelminthic treatment is<br />

recommended <strong>for</strong> pregnant women after the first trimester as part of<br />

worm infecti<strong>on</strong> reducti<strong>on</strong> programmes. x<br />

depending <strong>on</strong> previous tetanus vaccinati<strong>on</strong> exposure, to prevent ne<strong>on</strong>atal<br />

prophylaxis (PrEP)<br />

<strong>for</strong> HIV preventi<strong>on</strong><br />

C.6: In malaria-endemic areas in Africa, intermittent preventive<br />

treatment with sulfadoxine-pyrimethamine (IPTp-SP) is recommended<br />

<strong>for</strong> all pregnant women. Dosing should start in the sec<strong>on</strong>d trimester, and<br />

doses should be given at least <strong>on</strong>e m<strong>on</strong>th apart, with the objective of<br />

ensuring that at least three doses are received. z<br />

C.7: Oral pre-exposure prophylaxis (PrEP) c<strong>on</strong>taining tenofovir disoproxil<br />

fumarate (TDF) should be offered as an additi<strong>on</strong>al preventi<strong>on</strong> choice<br />

<strong>for</strong> pregnant women at substantial risk of HIV infecti<strong>on</strong> as part of<br />

combinati<strong>on</strong> preventi<strong>on</strong> approaches. aa<br />

(2016, in press).<br />

y. This recommendati<strong>on</strong> is c<strong>on</strong>sistent with the <str<strong>on</strong>g>WHO</str<strong>on</strong>g> guideline <strong>on</strong> Maternal immunizati<strong>on</strong> against tetanus (2006). The dosing schedule<br />

depends <strong>on</strong> the previous tetanus vaccinati<strong>on</strong> exposure.<br />

z. Integrated from the <str<strong>on</strong>g>WHO</str<strong>on</strong>g> publicati<strong>on</strong> Guidelines <strong>for</strong> the treatment of malaria (2015), which also states: “<str<strong>on</strong>g>WHO</str<strong>on</strong>g> recommends that, in areas<br />

of moderate-to-high malaria transmissi<strong>on</strong> of Africa, IPTp-SP be given to all pregnant women at each scheduled ANC visit, starting as<br />

early as possible in the sec<strong>on</strong>d trimester, provided that the doses of SP are given at least 1 m<strong>on</strong>th apart. <str<strong>on</strong>g>WHO</str<strong>on</strong>g> recommends a package of<br />

interventi<strong>on</strong>s <strong>for</strong> preventing malaria during <strong>pregnancy</strong>, which includes promoti<strong>on</strong> and use of insecticide-treated nets, as well as IPTp-SP”.<br />

To ensure that pregnant women in endemic areas start IPTp-SP as early as possible in the sec<strong>on</strong>d trimester, policy-makers should ensure<br />

health system c<strong>on</strong>tact with women at 13 weeks of gestati<strong>on</strong>.<br />

aa. Integrated from the <str<strong>on</strong>g>WHO</str<strong>on</strong>g> publicati<strong>on</strong> Guideline <strong>on</strong> when to start antiretroviral therapy and <strong>on</strong> pre-exposure prophylaxis <strong>for</strong> HIV (2015).<br />

Substantial risk of HIV infecti<strong>on</strong> is defined by an incidence of HIV infecti<strong>on</strong> in the absence of PrEP that is sufficiently high (> 3%<br />

incidence) to make offering PrEP potentially cost-saving (or cost-effective). Offering PrEP to people at substantial risk of HIV infecti<strong>on</strong><br />

maximizes the benefits relative to the risks and costs.<br />
