Current concepts in thoracic drainage systems.

Thoracic drainage systems are currently marketed in many varieties, resulting in significant cost and complicating patient management. Realistic needs have been identified from a survey of thoracic surgeons. These are: (1) clear plastic chest catheters with multiple drainage holes in sizes 28, 32, and 36F for adults and 16, 20, and 24F for infants and children; (2) serrated plastic connectors that can be sized at operation; (3) connecting tubes of clear plastic 6 feet long with a diameter of 1/2 inch; (4) a single graduated volume-collecting bottle of 1- to 2-liter capacity that can be emptied and marked, with a separate waterseal component and an associated manometer; and (5) a highflow vacuum source. A drainage system with these characteristics should be safe, effective, simple, and less costly.

A closed irrigation and drainage system for use with percutaneous abscess drainage: technical note.

A closed irrigation and drainage system has been used in 50 consecutive patients to assess its effectiveness in maintaining catheter patency and draining fluid collections. It consists of an irrigation fluid source, flushing syringe, drainage bag, and tubing to connect the components, and is assembled when the initial drainage procedure is performed. The system emphasizes the use of the siphon effect to maintain constant suction and a closed irrigation and drainage configuration that prevents spread of infection to others and minimizes contamination of the drained cavity. This method of irrigation and drainage also makes patient care considerably easier, and ensures catheter patency.

The corpus cavernosum intercommunicating venous drainage system.

A series of cavernosograms were used to study the corpus cavernosum superficial and deep dorsal venous system. Within this drainage system exists an intricate circumflex venous interconnective network of vessels. In addition, each corpus cavernosum intercommunicates with its opposite corpus cavernosum through median septal apertures. The cavernosum venous system, unlike the venous drainage from the glans penis, delays venous drainage and in doing so assists in maintaining erections.

Lacrimal drainage system injury in functional endoscopic sinus surgery. Incidence, analysis, and prevention.

Injury to the lacrimal drainage system with resultant epiphora is a complication of functional endoscopic sinus surgery. A study of 24 patients was conducted to determine the incidence and significance of lacrimal drainage system injuries during functional endoscopic sinus surgery. Intraoperative testing demonstrated seven occult injuries (15%) in 46 endoscopic procedures. Postoperative testing demonstrated diversion of lacrimal drainage into the middle meatus in two patients and spontaneous healing of the injured lacrimal drainage system with restoration of normal drainage in three of the patients available for follow-up testing. In no patient did epiphora develop. It is concluded that the nasolacrimal drainage system is in close proximity to the dissection cavity during functional endoscopic sinus surgery and, hence, is at risk for inadvertent injury. Occult damage to the nasolacrimal drainage system would appear to be a common event during functional endoscopic sinus surgery; however, the complication of postoperative epiphora is rare.

Bacteriologically stressed animal model of new closed catheter drainage system with microbicidal outlet tube.

We have used a catheterized rabbit model to test a newly developed catheter drainage system that incorporates a microbicidal outlet tube. In these tests, this new system was compared with a currently marketed closed drainage system, with daily challenge at the outlet tube using an auxotrophically marked uropathogenic strain of Escherichia coli. In the control series (silicone catheter connected to a standard drainage bag via a tamper-evidence seal) the challenge organism developed upstream biofilm colonization of the luminal surfaces of the catheter and drainage system that was complete in 4.6 +/- 2.1 days in 11 animals, while in 1 animal a rapid overgrowth of the system with Streptococcus faecalis developed. The presence of organisms other than the marked E. coli strain on the luminal surfaces of these control catheters showed that down stream colonization was also operative. In the test catheter drainage series, the microbicidal outlet tube insert precluded upstream colonization by the challenge organism in 12 of 16 catheters and significantly delayed (7.2 +/- 1.0 days) this colonization in the remaining 4 animals. When upstream colonization by exogenous bacteria was precluded by this effective device, downstream colonization of the drainage system by mixed populations of bacteria that probably migrated into the bladder via the extraluminal urethral route developed in some animals (6 of 16).

Evaluation of a vented drainage system in prevention of bacteriuria.

A vented urinary drainage system was compared to an otherwise identical non-vented system in a prospective, randomized, double-blind study. Among the 316 female patients evaluated there was a significant reduction in the rate of bacteriuria after 10 days using the vented system (66 per cent in the non-vented group versus 26 per cent in the vented group, p less than 0.05), while no significant difference could be demonstrated among the 190 male patients. We used urine hemoglobin as an indicator of mucosal trauma that might predispose to bacteriuria and no significant difference could be shown between the 2 drainage systems.

An analysis of the venous drainage system as a factor in hemorrhage from arteriovenous malformations.

The authors studied the venous drainage system and its impairment in relation to risk of hemorrhage in 108 cases of supratentorial arteriovenous malformation (AVM). The proportion of AVM's undergoing hemorrhage (hemorrhagic rate) was calculated in relation to: 1) the number of draining veins (one, two, or three or more); 2) the presence or absence of impairment in venous drainage (severe stenosis or occlusion in draining veins); and 3) the location of draining veins (deep venous drainage alone, superficial venous drainage alone, or a combination of the two). Statistical analysis demonstrated that AVM's with the following characteristics had a high risk of hemorrhage: 1) one draining vein (hemorrhagic rate 89% in 54 patients); 2) severely impaired venous drainage (hemorrhagic rate 94% in 18 patients); and 3) deep venous drainage alone (hemorrhagic rate 94% in 32 patients). The present study suggests that the venous drainage system of AVM's is significantly associated with the risk of hemorrhage of these lesions. Therefore, careful preoperative angiographic evaluation of the venous drainage system is mandatory for decision making in the management of patients with AVM's.

Prophylaxis of indwelling urethral catheter infection: clinical experience with a modified Foley catheter and drainage system.

With the application of the oligodynamic bactericidal property of silver ions, modification of the urinary catheter and drainage system has been found effective in the prevention of urinary tract infections owing to prolonged bladder catheterization. The newly devised catheter and open drainage system were used in 102 patients for bladder catheterization postoperatively or in those with urinary retention for periods ranging from 4 to 77 days. During the period of indwelling catheterization usually no antibiotics were administered and no patient had overt bacteriuria (more than 10(5) bacteria per ml.) or symptoms of urethritis. In contrast, all 20 patients in the control group who had the conventional type of indwelling catheters had bacteriuria within 4 days of catheterization. The data obtained indicate that effective prevention of urinary tract infection, which frequently is associated with indwelling urethral catheterization, can be achieved by the use of the modified catheter and drainage system.

[Ultramicroscopic studies on the drainage system of the human corpus luteum].

The granulosa lutein cells of the human corpus luteum have a specialized system of drainage with a particularly formed extracellular space, by which the steroids pass into the capillary vessels. The extracellular space consists of two partial systems: First one finds, similar to the bile capillaries of the liver, lacune-like widnings of the intercellular space, where numerous microvilli of the lining cells are to be found and which are lined by desmosomes and invaginations of the cell membrane. Second there exist relatively wide canals limited by a granular membrane forming a network of their own among the lutein cells. Both systems contact without direct communication. We believe that first the steroids pass into the intracellular lacunes by diffusion or active transport from where they reach the membrane-lined canals by help of the network they pass on to the pericapillar space from where they diffuse into the blood vessels.

Definitive treatment of chronic subdural hematoma by twist-drill craniostomy and closed-system drainage.

A simple method of bedside twist-drill craniostomy and closed-system drainage for evacuation of chronic and subactue subdural hematoma is introduced. The principles and theoretical considerations that form the basis for this technique are discussed. The technique was used in 21 patients with chronic or subacute subdural hematoma; it has produced results superior to those of the conventional methods used in our patient population. Possible mechanism responsible for the better results with the simple twist-drill closed-system drainage are described.

Lacrimal drainage system obstruction: management and results obtained in 70 patients.

Causes and types of acquired obstruction of the lacrimal drainage system are discussed in 70 patients, as well as the results of their surgical treatment. Obstruction of the lacrimal drainage pathway, according to frequency, was due to: trauma (mainly naso-orbital and LeFort II fractures), post-inflammatory stenosis of the nasolacrimal duct, tumours and latrogenic injuries of the naso-lacrimal drainage system often following Caldwell-Luc operations of the maxillary sinus. The ages of patients ranged from 3-70 years. Canalicular obstruction was diagnosed in 9 (12.9%), obstruction of the lacrimal sac in 2 (2.8%), while obstruction of the naso-lacrimal duct in 50 (71.4%) patients, including 3 bilaterally. And in 9 (12.9%) patients, injury to the lacrimal system following excision of tumours of the eyelids and the medial canthal region occurred. In patients with canalicular obstruction intubation of the canaliculi was carried out and both ends of the drain were inserted into the nasal cavity for 6 months via a dacryocystorhinostomy. Total recovery was obtained in 44.5%. In lacrimal sac and nasolacrimal duct obstruction Dupuy-Dutemp's dacryocystorhinostomy was performed and 90.4% of the patients recovered. When fibrosis or extensive damage of the lacrimal sac had occurred, wide anastomosis with the nasal duct was indicated. After tumour excision, the lacrimal pathways were reconstructed by conjunctivo-rhinostomy, conjunctivo-sinusostomy or conjunctivo-dacryocystorhinostomy. In 40% of the patients who underwent conjunctivo-dacryocystorhinostomy a successful outcome ensued.

[Acute epidural hematoma following evacuation of chronic subdural hematoma with continuous closed system drainage].

The authors report a case of acute epidural hematoma occurring after evacuation of chronic subdural hematoma with continuous closed system drainage. Laboratory data of the patient including bleeding time were within normal limits. The cause of the postoperative intracranial hematoma was the rapid surgical decompression of the initial lesion, and we considered that it could be prevented if chronic subdural hematoma was treated using closed system drainage and slow decompression. But acute epidural hematoma occurred after this operative procedure and it was accelerated by evacuation of the chronic subdural hematoma through the drain. An emergent craniotomy and removal of the hematoma was performed, so the patient was discharged from hospital with satisfactory neurological recovery. A careful check of the evacuated hematoma volume is very important, and CT scanning should be immediately performed if postoperative hematoma is suspected.

Contamination of underwater seal drainage systems in thoracic surgery.

The incidence of bacteriological contamination of drainage fluid (water constituting the underwater seal plus drainage effluent) was studied in 38 patients (50 chest drains), up to 6 days after thoracotomy. No bacteriological contamination was demonstrated in any of the samples taken during this period of time. We conclude that the underwater seal drainage system may be left for up to 6 days postoperatively without change of any of its components and without risk of contamination.

Upper airway oedema following autologous blood transfusion from a wound drainage system.

We report a case of a 70-yr-old white woman who underwent a revision of a total hip arthroplasty under general anaesthesia. The intraoperative course was stable without any complications and the estimated blood loss was 2500 ml. The patient received an autologous transfusion of blood from a wound drainage system in the recovery room. The transfusion was followed immediately by marked respiratory distress and upper airway oedema. She required emergency tracheal intubation and mechanical pulmonary ventilation. A coagulopathy also developed which was treated and resolved within 12 hr of the capillary leak phenomenon. The trachea was extubated on the first postoperative day and she had an uneventful course until discharge from the hospital two days later. We discuss the possible, aetiology of such a reaction to autologous blood including complement and platelet activation. It is suggested that reinfusion of nonwashed shed blood from a wound drainage system may present a hazard even though the fluid was autologous in origin.

Silicone tube intubation of the lacrimal drainage system.

We report 158 silicone tubes placed in the lacrimal drainage systems in 150 patients. Intubation is indicated in the following: congenital nasolacrimal duct obstruction, fresh canalicular lacerations, primary canalicular disease, complicated dacryocystorhinostomies, canaliculorhinostomies, and failed dacryocystorhinostomies. The procedure may be useful prophylactically before surgery or radiation of the medial canthal region.
