Murphy drip


A Murphy drip is a rectal infusion apparatus to administer the medical procedure of , also known as rectoclysis. During the procedure, an end of the Murphy drip is inserted into the rectum and large quantities of liquid are infused into the rectum drop by drop. Prior to fluids or medicines being given intravenously, the Murphy drip and hypodermoclysis were the prime routes to administer fluids such as for replacement when patients could not be fed by mouth.Wisconsin surgeon John Benjamin Murphy introduced the drip method of saline infusion per rectum in the treatment of peritonitis.

The Murphy drip was invented by Wisconsin surgeon John Benjamin Murphy, for the purpose of administering a proctoclysis for hydration and replenishment of electrolytes, via a sodium and calcium chloride solution. This would be used when administration by mouth was not possible because of the condition of the patient. The Murphy drip was described in the April 1909 issue of the Journal of the American Medical Association. By as early as July 1928, the Murphy drip was considered an auxiliary method of injection behind intravenous therapy and subcutaneous injection, the two principal methods of injection at that time.

The Murphy drip can be used for administering drugs by this route and the apparatus is also used in conjunction with a catheter for bladder irrigation. The term can even be applied to apparatus used to administer fluids intravenously.
