**1. Introduction**

Haemodialysis was first done successfully in humans, in 1945, and since then a lot of technological advancements have been made [1].

There are still common acute complications that are encountered by physicians during their routine practice. The common complications include intradialytic hypotension and hypertension, muscle cramps, clotting of the circuit and dialyzer reactions. Some are severe and lead to increase mortality of the patients hence they need to be identified and treated early, some are mild, which again need early identification and management to avoid cumbersome tests and intervention. These are discussed briefly below, under systematic headings.
