What are the 4 T’s of PPH?
Tone 70%
Tissue 20%
Thrombin 1%
Trauma 9%
What is the main cause of PPH?
Atonic uterus 70-90%, with or without retained product
What is a prevention of PPH?
identify risk factors
active 3rd stage reduces risk of PPH by 66%
Initial sentences???
Requires prompt initiation of multiple simultaneous actions
Upon recognising a PPH what should be the first actions??
Call for help
SOAPS
Haematologist
bloodbank
What is the immediate action requires irrespective of cause?
Lie flat
high flow O2 (15L) non rebreathable mask
keep warm
OBS- MEOWs
SATS, RR, pulse, BP, Temp, capillary refill
Catheterise- empty bladder measure - urometer - fluid balance
2x IV access - urgent bloods - FBC, U&E, G&S, LFT, Xmatch 4 units
consider CVP
rub up contraction - expel clots
Fluid resuscitation:
2L of crystalloid hartmans or 0.9% sodium chloride warm
consider blood products
Xmatch ASAP otherwise
O neg - and clotting factors, cryocipitate, FFP, Platlets
What are the signs for maternal shock? and what could this suggest?
Maternal tachy 100bmp> resps 30> capillary refill 2seconds> indication of significant blood loss If syst <100 indicated 25% blood loss
What is involved in assessment?
EBL
OBs- shock
Clinical hist
4 T’s
Whats should you do to stop the bleeding manually?
Uterine massage- expel clots- bimanual compression
Apply pressure to tears/epis - repair
Retained products- manual removal if necessary
Thrombin - give blood products
What first line drugs should be given?
If third stage has been actively managed and bleeding continues repeat dose can be given
10IU of sytocinon
1 ampule sytometrine
If uterus contracts begin sytocinon infusion:
40IU syntocinon in 500mls of 0.9 sodium chloride
125mls/hr over 4hours
Consider Tranexamic acid 1g slow IV
if bleeding continues 30mins or reoccurred <24hours repeat dose

Carboprost 250mcg up to eight doses at 15min intervals
Misoprostal 600-1000mcg sublingual or PR
What are the mechanical and surgical measures may be used to stop bleeding?
Balloon tamponade - uterine pressure and create tone Laparotomy - if abdo not open B-lynch intervention radiology uterine vessel and arterial ligation Hysterectomy - 40 per 100,000
