COMPLICATIONS?
Meconium Aspiration Syndrome:
Dark, greenish staining or streaking of the amniotic fluid or the obvious presence of meconium in the amniotic fluidLimpness in infant at birth
Antibiotics to treat infection
Breathing machine to keep the lungs inflatedUse of a warmer to maintain body temperature
Tapping on the chest to loosen secretionsIf there have been no signs of fetal distress during pregnancy and the baby is a vigorous full-term newborn, experts recommend against deep suctioning of the windpipe for fear of causing a certain type ofpneumonia.
The most accurate test to check for possible meconium aspiration involves looking for meconium staining on the vocal cords with a laryngoscope

PERTUSIS
Bordetella pertusis
IP 7 prior cough and -21 cough
paroxysmal cough with inspiratory whoop without FEVER mostly
1 week = CATARRAL FASE
2-3 week = paroxysmal fase
Infants less than 6 months of age are at greatest risk of complications (apnoea, severe pneumonia, encephalopathy) and are most commonly infected by spread from family members
PERTUSIS INVESTIGATIONS
Laboratory confirmation is not necessary for diagnosis, but may be helpful for infection control
A nasopharyngeal aspirate/swab for PCR is the investigation of choice. The test is usually negative after 21 days, or 5-7 days after effective antibiotic therapy has been commenced
Control of diagnosed case PERTUSIS
Vaccionation?
Exclude from school and presence of others outside the home (especially infants and young children) until received 5 days of therapy, or coughing for more than 21 days
Unimmunised or partially immunised children diagnosed with pertussis should still complete the pertussis immunisation schedule
Pertusis TX
Antibiotics
Consider antibiotics if:
Diagnosed in catarrhal or early paroxysmal phase (may reduce severity)
Cough for less than 14 days (may reduce spread; reduces school exclusion period)
Admitted to hospital
Complications (pneumonia, cyanosis, apnoea)
Antibiotic options:
Neonates:
Azithromycin 10 mg/kg oral daily for 5 days
Children who cannot swallow tablets:
Clarithromycin liquid 7.5 mg/kg/dose (max 500 mg) oral BD for 7 days
Children who can swallow tablets:
Azithromycin (for children = 6 months old): 10 mg/kg (max 500 mg) oral on day 1, then 5 mg/kg (max 250 mg) daily for 4 days
If macrolides are contraindicated:
Trimethoprim-sulphamethoxazole (8-40 mg per mL)
0.5 mL/kg (max 20 mL) BD for 7 days
PROFILAXIS PERTUSIS
Prophylaxis is aimed at preventing spread to infants <6 months
There is little evidence that antibiotics prevent transmission outside of household settings, and side effects (especially gastrointestinal) are relatively common
Transmission requires close contact (exposure within 1 metre for more than 1 hour) but can be less for young infants
Most school-aged children who are fully vaccinated and do not have symptoms do not require prophylaxis
Management of immunodeficient contacts should be made on a case by case basis
Management of outbreaks may differ from below and will be conducted by DHS
