Cardiovascular Disease. Patients with systemic hypertension, arteriosclerosis, and other cardiovascular diseases may be at risk when high concentrations of topically administered adrenergic agonists such as phenylephrine are used. Repeated topical doses or soaked cotton pledgets placed in the conjunctival sac have been associated with adverse cardiovascular effects. Likewise, P-blockers should be avoided or used cautiously in patients with congestive heart disease, severe bradycardia, and high-grade atrioventricular block. Topical P-blockers, however, may be used safely in patients with cardiac pacemakers.

The excision of small superficial conjimctival lesions, such as concretions, can usually be achieved with topical anesthesia alone.Two or three drops instilled at 1-minute intervals allow sufficient anesthesia for this purpose. Alternatively, a cotton pledget or cotton-tipped applicator soaked in anesthetic solution may be applied for 1 to 2 minutes before surgery.This local application allows anesthesia of deeper portions of the conjimctiva. 

Figure 19-4 Lifting the conjunctiva with tissue forceps exposing the subconjunctival space before injection is better tolerated if an anesthetic-soaked cotton pledget is applied to the area first.

Pseudomonas bacteremia has been attributed to the use of material in open-heart surgery that was stored in accidentally contaminated benzalkonium solutions, and after cardiac catheterization caused by inadequate disinfection of the catheters with benzalkonium solutions. In 1961, about 15 patients were reported with Pseudomonas infections caused by cotton pledgets kept in a contaminated aqueous solution used for skin antisepsis before intravenous and intramuscular injection (8). In 1976 there were outbreaks of Pseudomonas cepacia infections in two American general hospitals (9) and pseudobacteremia Pseudomonas cepacia or Enterobacter) caused by contamination of blood cultures in 79 patients in whom contaminated aqueous benzalkonium solutions were used for skin and antisepsis before venepuncture and due to contamination of the samples (SEDA-11, 490) (10). 

Another indication for this technique is evaluation for a CSF leak after. surgery or trauma. One variation of evaluating fur a leak is to put cotton pledgets in the nostrils fur 24 hours and check for abnormal radioactivity on (he pledgets.

Closed systems NIPPV are unnecessary unless ventilatory drive is blunted by oxygen therapy, sedative medications, or excessive hypercapnia, which can lead to excessive air leakage from the nose or mouth (4). If necessary, one can provide an essentially closed system of ventilatory support by using a lipseal (Respironics International Inc., Murrysville, Pennsylvania, U.S.), placing cotton pledgets in the nostrils, and sealing the nostrils with a... 

Hold the syringe vertically and expel excess air, liquid, and bubbles into a cotton pledget (swab) moistened with the proper disinfectant, or into a small bottle of sterile cotton (209). 

When removing a syringe and needle from a rubber-stoppered bottle, wrap the needle and stopper in a cotton pledget moistened with the proper disinfectant (209). If there is danger of the disinfectant contaminating sensitive experiments, a sterile dry pledget may be used and discarded immediately into disinfectant solution.
