Surgical catheter

The authors claimed that this was the first report of this problem. Referring to the observation that baclofen injection into the cerebral ventricles can produce fever in rats (15), they assumed that rostral spread of baclofen could have initiated a thermoregulatory response via the chemo-trigger zone in the third ventricle. They suggested that a percutaneous subarachnoid catheter could facilitate the decision to either proceed with or abort surgical catheter or pump implantation when baclofen is associated with fever. 

Tests have been developed that test different products for their effectiveness as a healthcare personnel handwash (327) evaluate hand disinfectants for use in surgery (333) determine the effectiveness of a surgical hand scmb, ie, the glove juice test (311,329) evaluate antiseptics for the oral cavity to be used in mouthwashes (334,335) and test antiseptics for the periurethral area and appHcation to catheters (336,337). A method used for a test comparing four antiseptic products was adopted as recommended practice by the Association of Practitioners of Infection Control (338). 

A detailed clinical history, past medical and surgical history, medications, allergies, laboratory work-up, physical examination, and NIHSS should be obtained as quickly as possible for assessment of inclusion and exclusion criteria for lAT. Table 4.1 lists the criteria for catheter-based reperfusion therapy currently in place at the Massachusetts General Hospital (Table 4.1 see also www.acutestroke.com for updated criteria). 

Baboons were surgically prepared with chronically indwelling silastic catheters implanted in either femoral or jugular veins under pentobarbital or halothane anesthesia using methods described in detail by Lukas et al. 

A 43-year-old male in the surgical ICU after exploratory laparotomy following a motor vehicle accident develops fever that is unresponsive to broad-spectrum antibacterial therapy (piperacillin-tazobactam 3.75 g every 6 hours, gentamicin 120 mg every 8 hours, and vancomycin 1 g every 12 hours). The patient has a central venous catheter and a Foley catheter. Blood cultures are negative at the time, but the patient has yeast growing in the sputum and urine. Laboratory studies reveal a white blood cell count of 11,300 cells/mm3 (11.3 x 109/L). 

A large-diameter multihole urethral catheter should be inserted to facilitate saline lavage and evacuation of blood clots. Surgical removal of blood clots under anesthesia may be required if saline lavage is ineffective. Active bleeding from isolated areas may be cauterized with an electrode or laser. In severe cases that are unresponsive to local or systemic pharmacologic intervention,... 

The primary site of action of epidurally administered agents is on the spinal nerve roots. As with spinal anesthesia, the choice of drug to be used is determined primarily by the duration of anesthesia desired. However, when a catheter has been placed, short-acting drugs can be administered repeatedly. Bupivacaine is typically used when a long duration of surgical block is needed. Lidocaine is used most often for intermediate length procedures chloroprocaine is used when only a very short duration of anesthesia is required. 

Myocardial ischemia and infarction cause abnorma myocardial metabolism, decreased left ventricular (LV) systolic function, diastolic dysfunction, congestive heart failure, and decreased survival. Consequently, revascularization techniques, either surgical or catheter based, have become integral to treatment of severe ischemic heart disease. 

It was not until 1929 that the concept of central cardiac catheters came to being. Prior to this, it was felt that manipulation of the heart would lead to immediate death. Werner Forssmann, while a surgical fellow in Eberswald, Germany, believed there was a more efficient way to more rapidly... 

When continuous or intermittent intravenous infusion is required, a catheter is surgically implanted at least 5 days before the start of treatment. The animals are maintained on continuous infusion with physiological saline between implantation and the start of test item administration. 

Bleeding at superficial sites, such as venous injection sites, catheter insertion sites, venous cutdowns, arterial punctures, and sites of recent surgical procedures, gingival... 

Surgical revascularization (ie, coronary artery bypass grafting [CABG]) and catheter-based revascularization (ie, percutaneous coronary intervention [PCI]) are the primary methods for promptly restoring coronary blood flow and increasing oxygen supply to the myocardium.
