Safety devices to prevent airborne infection from clinical suction apparatus.

Infection related to clinical suction apparatus has been widely recognized. Safety systems available at present include devices to prevent overflow from collecting vessels and in-line air filters. The relative efficiency of these devices for the containment of aerosols generated within the collecting vessel has been evaluated. Although of increased resistance, filter capsules of 0.3-micron pore size prevented the passage of test aerosols for longer periods than the widely used 8-micron fibre filter tubes. Filter life can be prolonged by preventing overflow from collecting vessels and protecting against the passage of foam and froth.

Contamination of multi-use closed tracheal suction catheters: an in-vitro study.

The use of closed multi-use tracheal suction systems in ventilated patients is increasingly popular as it offers a number of potential physiological and microbiological advantages. As the use of these systems has been associated with an increased prevalence of tracheal colonization, effective self-cleaning mechanisms employed in these catheters are necessary. Using an in-vitro model we assessed the degree of catheter colonization in two multi-use catheter systems; Stericath and Trach-Care. Fifty of each catheter type were tested for colonization with five challenge organisms: Staphylococcus aureus (NCTC 6571); Pseudomonas aeruginosa (NCTC 10662); Haemophilus influenzae type b; S. epidermidis (slime producer); and S. epidermidis (slime non-producer). All five challenge strains had colonized both catheter types after 24 h and all 100 catheter tips were colonized. The extent and density of colonization was variable and interspecies variation in the pattern of catheter colonization was observed. The mean colonized lengths of Stericath catheters was 10.9 +/- 1.4 cm and of Trach-Care 2.7 +/- 1.3 cm (P < 0.0001).

An alternative method for securing suction drains.

A reliable method of securing suction drain tubing is presented. It ensures that the tubing lies flat on the skin and runs in the direction the surgeon wishes. The method uses an adhesive tape (Elastoplast) 'flag' on the tubing.

Waveform reliability of the phase related external suction baroreceptor manipulation method.

The phase related external suction (PRES) method of controlled carotid baroreceptor manipulation (a neck cuff with cardiac cycle timed pressure variations) has been used to investigate not only the human baroreflex, but extrahomeostatic effects of baroreceptor activity (such as the modulation of cortical activity, peripheral reflexes, and pain) as well. The present study provides quantitative within subject test-retest reliability estimates of PRES effects on 6-s trial-length heart rate waveforms. Mean within subject test-retest reliability for each averaged heart rate response waveform was 0.77 for the baroreceptor stimulation (systolic negative/diastolic positive cuff pressure) condition, 0.56 for the control condition (diastolic negative/systolic positive cuff pressure), and 0.69 for the difference between conditions. The importance of analyzing time-intensity dynamics, rather than merely the mean or maximum effect of any treatment variable is emphasized, and recommended for investigations of a wide variety of short duration, induced physiological time series processes.

Evaluation of two endotracheal suction regimes in babies ventilated for respiratory distress syndrome.

All low birthweight babies ventilated for the respiratory distress syndrome during a period of fourteen months were randomised to receive endotracheal suction 12-hourly or 6-hourly. There were no significant differences in respiratory outcome between the groups. These observations suggest that it is safe to aspirate endotracheal tubes infrequently during the first few days in uncomplicated respiratory distress syndrome.

Potential hazards of tracheobronchial suctioning.

Tracheobronchial suctioning is a routine practice frequently carried out in intensive care units (ICUs). It is required when the normal coughing mechanism is inadequate or disrupted; for example, where there is underlying respiratory or neurological disease, or where the cough is deliberately suppressed by sedative, muscle relaxants or anaesthetic agents while a patient is undergoing intermittent positive pressure ventilation. The procedure is carried out via a nasotracheal, orotracheal or tracheostomy tube. During the performance of this intervention, the skilled nurse is aware of the risks to which the patient is exposed and endeavours to prevent or minimise possible complications. In the following account of complications that may occur during or as a result of the procedure these have been classified as immediate, intermediate and later complications, as shown in Table 2. The purpose is to stimulate greater awareness of the hazards involved in this common everyday practice in intensive care units.

Effect of level of lung injury on HR, MAP and SaO2 changes during suctioning.

25 patients with documented lung injury were suctioned using a manual resuscitation bag (MRB) and a standardised procedure. Level of lung injury was not significantly correlated with changes from baseline in heart rate (HR) oxygen saturation (SaO2) or mean arterial pressure (MAP). However, HR and MAP increased significantly returning to baseline at 5 min. Patients' SaO2 did not change significantly during the procedure or up to 15 min afterwards. No changes in cardiac rhythm were found during the event or for 15 min afterwards. Standards for hyperoxygenation and hyperinflation could not be achieved using the MRB even with a standardised procedure.

Use of an apical heart suction device for exposure in lung transplantation.

Cardiopulmonary bypass is not necessary for the performance of bilateral sequential lung transplantation in most circumstances. Inadequate exposure to the left hilum is occasionally the sole indication for institution of cardiopulmonary bypass. We report the use of a suction heart positioning device to allow lifting of the heart for improvement of left hilar exposure. This technique has decreased the need for cardiopulmonary bypass when bypass is indicated due to difficult operative exposure.

Suction dressings to secure a dermal substitute.

One of the problems with the dermal substitute Integra has been securing the material to the wound bed to prevent shearing and loss. Techniques to achieve stability include staples and elastic netting with an over layer of absorbent dressings that can be changed regularly. We report an effective technique using suction dressings to immobilise Integra. This technique led to firm application underlying tissue, and appeared to decrease fluid collection under the Integra. Earlier mobilisation and discharge from hospital were facilitated.

Clinical judgments about endotracheal suctioning: what cues do expert pediatric critical care nurses consider?

Making accurate and timely judgments based on multiple ways of knowing is an essential skill in critical care nursing practice. Studies have proposed that positive patient outcomes are linked to expert judgments in a variety of critical care situations; however, little is known about clinical judgments related to specific critical care nursing interventions. This article presents a qualitative nursing research study which examined the cues that expert pediatric critical care nurses used in making clinical judgments about suctioning intubated and ventilated, critically ill children. The participants' words and actions attest that the 'sensing' and 'thinking' of the process of cue use, are interwoven with, and integral to, the 'doing,' which is the process of skilled performance.

Day-case adenoidectomy: outcomes are improved using suction coagulation and prophylactic anti-emetic treatment.

In 2004, the Department of Health published 10 High Impact Changes across the NHS. Of these, the first was treating day surgery as the norm for elective operations, releasing up to half a million in-patient beds each year. Adenoidectomy is an operation commonly performed in children for upper respiratory tract obstruction and as part of the surgical management of otitis media with effusion. Many surgeons consider the traditional curettage adenoidectomy as an unsatisfactory operation because it is performed blind, and is associated with varying reported levels of post-operative bleeding. Concern about the risk of bleeding and the frequent occurrence of post-operative nausea and vomiting have discouraged many surgeons from adopting adenoidectomy as a day-case procedure. We have audited the management and discharge of a cohort of 72 children undergoing traditional curettage adenoidectomy. Based on the results, we have completed the audit loop, by managing a second cohort of 77 children by suction coagulation adenoidectomy. An anaesthetic protocol has been designed to reduce post-operative nausea and vomiting, and facilitate same day discharge from hospital. The rate of post-operative nausea and vomiting fell from 21 to 1.3%, and the post-operative bleeding from 9.7% to nil. Discharge on the day of operation rose from 40.3 to 100%. Our audit confirms that these measures permit safe, day-case adenoidectomy.

Compartment syndrome caused by suction.

Compartment syndrome is probably underdiagnosed particularly when the mechanism of injury is indirect. This case is unusual in that the syndrome occurred as a consequence of suction injury and illustrates the benefits of early tissue pressure measurement and surgical decompression.

Airway management with the Laryngeal Tube Suction II in a patient with cervical spine injury.

Supraglottic airway devices may offer alternative strategies for securing the airway in patients with cervical spine injuries. A case of airway management with the LTS II, a modified version of the laryngeal tube suction, in a patient with a paramedian atlas fracture scheduled for decompression of a haematoma on the forehead is described. Device insertion was successful in the first attempt and a gastric tube was inserted without problems. Ventilation was uneventful, no complaints were stated after surgery.

Closed suction pelvic drainage after radical pelvic surgical procedures.

Thirty-four women had short-term, low-pressure, closed suction pelvic drainage after radical gynecologic surgical procedures. Mean collected fluid losses were significantly higher after radical hysterectomy (25.3 ml/kg) when compared with abdominal hysterectomy (10.7 ml/kg) and lymphadenectomy. There was no correlation between the volume of pelvic drainage and patient's age, patient's weight, duration of operation, or amount of blood loss. The fluid contents resembled serum and were rarely culture positive. Short-term (5-day) drainage was not associated with lymphocysts.
