Anti-shock garment in postpartum haemorrhage

The non-pneumatic anti-shock garment (NASG) is a first-aid device that reverses hypovolaemic shock and decreases obstetric haemorrhage. It consists of articulated neoprene segments that close tightly with Velcro™, shunting blood from the lower body to the core organs, elevating blood pressure and increasing preload and cardiac output. This chapter describes the controversial history of the predecessors of NASG, pneumatic anti-shock garments (PASGs), relates case studies of PASG for obstetric haemorrhage, compares pneumatic and non-pneumatic devices and posits why the NASG is more appropriate for low-resource settings. This chapter discusses the only evidence available about NASGs for obstetric haemorrhage – two pre-post pilot trials and three case series – and describes recently initiated randomized cluster trials in Africa. Instructions and an algorithm for ASGs in haemorrhage and shock management are included. Much remains unknown about the NASG, a promising intervention for obstetric haemorrhage management.
