Abstract

The cannula of a conventional intravascular catheter is placed into the peritoneal cavity through a small shallow incision in antiseptically prepared skin. The stylet or trocar of the conventional catheter is removed; and a stainless steel elongated flexible guide is inserted through the catheter'"'"'s cannula into the peritoneal cavity. The catheter'"'"'s cannula is removed and a flexible elongated cannula inserted into the cavity over the guide and secured in place with a suture. Fluid operation means is connected to the elongated cannula by connector means to permit fluid treatment after removal of the guide. Apparatus to effect peritoneal fluid treatment are placed in sterile openable sealed packages for storage and transport.

Claims

1. A method for peritoneal fluid treatment in which:

a portion of the skin surface about the peritoneum is sterilized using skin preparation means;

a local anesthetic is administered to said sterilized skin surface;

a nick-type incision is made in the area of said sterilized skin using incision means;

a hollow first cannula is placed through said incision and just slightly into the peritoneal cavity;

flexible guide means is inserted into the peritoneal cavity through said first cannula well into said cavity, said guide means being from about 20 to 50 centimeters in length and from about 0.5 millimeters to about 2 millimeters in diameter for insertion into the peritoneal cavity through said first cannula, said guide means being sized in cross-section to fit within said first cannula and in length to be substantially longer than said first cannula, said guide means having a first end which is blunt for insertion into the peritoneal cavity, and said guide means being a stainless steel piano-wire-like wire made of a refractory metal having substantial flexibility from its first end to a point from about one-third to one-half the length of said guide means measured from said first end and thereafter said guide means has less flexibility along its length to its second end;

said first cannula is removed leaving said guide means inserted;

a second cannula which is elongated and flexible is inserted into the peritoneal cavity over said guide means, said second cannula being a flexible plastic-like tube having a plurality of spaced apart apertures formed in it from its second end to a point about one-third to one-half along its length;

said guide means is removed; and

fluid operation means is connected to said second cannula by connector means adapted to one end of said cannula to effect fluid treatment operations.

2. The method of claim 1 wherein said fluid operation means includes an aspirator and fluid container, said aspirator being first connected to said second cannula and operated to extract fluid from said peritoneum which is evaluated for diagnostic indicia and upon the absence of such indicia said aspirator is disconnected from and said fluid container is connected to said second cannula for injection and extraction of lavage fluid.
