Use of closed-suction drains to treat generalized peritonitis in dogs and cats: 40 cases (1997-1999).

OBJECTIVE: To determine outcome of dogs and cats with generalized peritonitis treated by means of closed-suction drainage. DESIGN: Retrospective study. ANIMALS: 30 dogs and 10 cats with generalized peritonitis. PROCEDURE: Medical records were reviewed, and information on signalment, clinicopathologic abnormalities, contamination source, results of microbial culture, surgical procedure performed, postoperative management, complications, and outcome was obtained. RESULTS: The gastrointestinal tract was the most common source of contamination. Abdominal fluid collected from 34 patients at the time of surgery was submitted for bacterial culture; results were positive for 28 (82%). The most commonly isolated organism was Escherichia coli. Postoperative complications included anemia (n = 21), hypoproteinemia (21), vomiting (9), edema (7), and diarrhea (5). Total solids concentration did not decrease during the first 48 hours after surgery, and all drains remained functional until removal. Twenty-eight patients survived to the time of discharge; 8 of the 12 animals that died did so within 18 hours after surgery. The only factor significantly different between patients that survived and patients that died was postoperative systolic blood pressure. Factors that were not significantly associated with outcome included detection of bacteria in the abdominal fluid, number of organisms cultured from the abdominal fluid, selection of antimicrobials for empiric treatment, and source of contamination. CONCLUSIONS AND CLINICAL RELEVANCE: Results suggest that closed-suction drainage may be a useful method for treating generalized peritonitis in dogs and cats. No clinically important complications were associated with their use.

Intravesical pressure during transurethral resection using Iglesias resectoscope with continuous irrigation and suction.

Intravesical pressure was studied in 20 patients during transurethral resection (TUR) of the prostate using the Iglesias resectoscope with continuous irrigation and suction. The suction pressure (50 cm H20) was considerably lower than that suggested by Iglesias. The amount of irrigant was thereby appreciably diminished and blocking of the outlet system was avoided. The intravesical pressure averaged 35 cm H20 during resection, which is less than in conventional resection, and 15 cm during evacuation of tissue chips. Signs of TUR syndrome were not seen. We consider the new resectoscope to be a considerable improvement for TUR.

Epithelialization and blood flow in suction blister wounds on healthy volunteers.

Epithelialization and blood flow in painlessly inflicted small suction blister wounds were studied in healthy volunteers (n = 26) using evaporimetry and laser Doppler flowmetry (LDF), respectively. As expected, the evaporation rate normalized faster in wounds covered by an occlusive film than in wounds covered with gauze. The evaporimetry technique was found to be a simple alternative to the biopsy-based methods that have previously been used in humans. Blood flow was increased after 25 min of suctioning, and the hyperemia increased further after equalization to atmospheric pressure. This wound hyperemia (day 1) was more pronounced than that observed during heating of adjacent skin, and more pronounced at a pressure of 400 mm Hg below atmospheric pressure than at 200 mm Hg below. The hyperemic response lasted for some days and was similar on arm and foot. A mechanical LDF linear scanner was used to create a flow profile across the wound into the adjacent skin. Six months after inflicting the lesions there was no visible scar. The findings suggest that this blister wound model may be useful for studying epithelialization and microcirculatory events after trauma and during early wound healing in humans.

Continuous suction and intermittent irrigation for septic coxitis.

This prospective study was undertaken on 42 children with septic arthritis of the hip diagnosed within 5 days of onset of symptoms. The mode of treatment used was continuous catheter suction and intermittent saline irrigation of the hip joint together with parenteral antibiotics. All but 4 children responded to this treatment; 2 of these were less than 3 years old. We conclude that continuous suction-irrigation is effective in children older than 3 years very early in the course of the disease; the majority need not undergo arthrotomy.

Suction decompression of aneurysms. Technical note.

A technique utilizing suction decompression of large aneurysms to allow safer application of a clip is described. Large aneurysms are punctured with a No. 21 scalp vein needle attached to the operating room suction device. This procedure causes relaxation of the aneurysm itself and allows safer application of the clip. The technique has been used in six cases of giant aneurysms.

A serrated suction tip for tumor removal. Technical note.

A serrated suction tip with a variety of diameters and serrations has been developed for the microsurgical removal of tumors. These tips can dissect and aspirate tumor tissue, cerebrospinal fluid, or blood simultaneously, and the degree of suction can be controlled by the pressure of the tip against the tumor.

A newly designed puncture needle for suction decompression of giant aneurysms. Technical note.

A newly designed puncture needle for aspirating large or giant aneurysms is described. This puncture needle represents a modification of an intravenous catheter with an internal needle. It is designed to prevent blood from leaking when the internal needle is removed and has a lateral tube for aspiration. Following aneurysm puncture with the parent artery temporarily trapped, the catheter is positioned on the head frame with a brain spatula and a self-retaining retractor. Blood is suctioned through the lateral tube with a syringe or the suction system normally used in the operating room.

The use of postoperative suction drainage in total hip arthroplasty.

Two hundred eight primary total hip arthroplasties were reviewed to evaluate the effect of closed suction drainage. This review included 45 hips in which closed drains were used and 163 hips in which drains were not used. These two groups were compared for possible differences in wound problems, temperature elevations, changes in Hgb/Hct, and the need for transfusions. There was no statistically significant difference in postoperative temperatures or decrease in Hgb. However, there were four superficial wound infections in the drained group and three superficial wound infections in the non-drained group (P < .025). There were no deep infections in either group. These findings suggest closed suction drainage provides no apparent advantage in uncomplicated primary total hip arthroplasty.

Ventilator versus manual resuscitation bag as the method for delivering hyperoxygenation before endotracheal suctioning.

A critical review and analysis of the current research on the efficacy of the ventilator versus the manual resuscitation bag (MRB) as the method of delivering hyperoxygenation/hyperinflation breaths before, during, and/or after endotracheal suctioning (ETS) is presented. Current research findings indicate that hyperoxygenation/hyperinflation breaths at 100% oxygen (O2) delivered via the ventilator have resulted in elevated blood-O2 levels which are either superior or equivalent to the MRB in preventing suction-induced hypoxemia. Delivery of hyperoxygenation/hyperinflation breaths using the MRB results in increased airway pressure, and increased hemodynamic consequences. Guidelines of clinical practice, based on current research findings, are presented. Areas for further research are identified.

Closed tracheal suction systems: effectiveness and nursing implications.

Closed tracheal suction systems (CTSS) are currently being used to minimize complications associated with endotracheal suctioning. Advantages of CTSS include improved oxygenation, decreased clinical signs of hypoxemia, maintenance of positive end-expiratory pressure, infection control, convenience, cost, and reduced patient anxiety. Some concerns related to use of CTSS include autocontamination, decreased effectiveness, difficult to use, excess negative pressure, and airway trauma. Strategies for reducing these and other concerns are shared. Recommendations for nursing practice and nursing research are discussed.

Suctioning techniques for the removal of respiratory secretions.

Suctioning techniques are a necessary nursing intervention to remove respiratory secretions and maintain optimum ventilation and oxygenation in patients who are unable to get rid of these secretions independently. This intervention can induce problems and it is important that the correct procedure is adhered to so that patient safety and comfort are maintained. Nurses should be competent in assessing the need for suction. The decision to perform this procedure should be based on the patient's clinical signs and symptoms and should not be undertaken as a matter of routine.

Endotracheal tube narrowing after closed-system suctioning: prevalence and risk factors.

BACKGROUND: Few data exist about buildup of secretions within endotracheal tubes of patients treated with closed-system suctioning in the intensive care unit. OBJECTIVES: To describe the extent, prevalence, and distribution of narrowing of endotracheal tubes related to buildup of secretions and to determine contributing factors. METHODS: Forty endotracheal tubes were examined within 4 hours of extubation, after at least 72 hours of use. Data on patients' daily weight and fluid balance, ventilator humidification temperatures, and nurses' descriptions of secretions during the 3 days preceding extubation were recorded. Any secretion debris in the endotracheal tubes was weighed. At 1-cm intervals along the tube, the debris was described and the depth of the debris was measured to the nearest 0.5 mm. RESULTS: Mean duration of intubation was 6.6 days. Two tubes had no debris. Mean overall depth of debris was 0.64 mm, mean greatest depth was 2.0 mm (range, 0-5 mm), and mean weight was 1.16 g. The entire tube was affected, with the greatest depth of debris at the 6- to 9-cm and 13- to 14-cm markings. Duration of intubation correlated with mean greatest depth of debris (r = 0.37, P = .02), mean overall depth of debris (r = 0.48, P = .002), and mean weight of debris (r = 0.38, P = .02). CONCLUSIONS: Endotracheal tubes are markedly narrowed by the buildup of secretions after closed-system suctioning. Duration of intubation, but not endotracheal tube size or amount of secretions, was associated with the degree of narrowing.

[Transnasal microsurgery using a micro-pressure-suction-irrigation system for pituitary adenomas].

Micro-pressure-suction-irrigation system (MPSIS), introduced by Luedecke et al, is an instrumentation for the direct transnasal pituitary procedure. We improved this system for use in Japan. The irrigation system can effectively clean the operating field by one-hand manipulation and dissect tumor tissue by its rapid flow. The pressure of suction and irrigation can be adjusted respectively by a device in the handpiece. The MPSIS is applicable to different stages of intervention because it is equipped with separate tips of various diameters, lengths and angles. This system is especially useful in combination with a micromirror or an endoscopy for direct inspection of the eccentric tumor sites such as the cavernous sinus, the upper part of the planum sphenoidale, or the posterior suprasellar regions. The use of the MPSIS helps to avoid injury to normal tissue structures, and prevents tiny soft microadenoma from being lost during preparation. We have proved the suitability and usefulness of the MPSIS in 23 surgical interventions for transnasal microsurgery of pituitary adenomas.

Comparing ultrasound-assisted lipoplasty with suction-assisted lipoplasty.

Ultrasound-assisted lipoplasty (UAL) implies that ultrasound energy is applied directly to adipose tissue by means of a probe or cannula, resulting in emulsification of fat. UAL can be performed with either a solid probe or a hollow titanium cannula that vibrates at ultrasonic frequency. Suction-assisted lipoplasty (SAL) implies that adipose tissue is removed from the subcutaneous space by means of a traditional blunt-tip hollow cannula attached to high-power suction. The purpose of this article is not to debate the merits of one technique over the other; it is simply to compare UAL and SAL from a technical standpoint. Given that most plastic surgeons are familiar with SAL and that UAL is still relatively new to US plastic surgeons, the comparison is intended as a jumping board for those who are already proficient at SAL technique who may be interested in expanding their surgical armamentarium. UAL is not a replacement for SAL; it is more an extension of SAL technique.

Assessing the need for endotracheal suction.

Endotracheal suction (ETS) is a common method used to remove broncho-pulmonary secretions. This study aimed to investigate whether, and how, nurses in the paediatric intensive care environment assess the need for endotracheal suction. Overt, non-participant observation and interviews were used to collect data from 12 nurses on four paediatric intensive care units. The large majority of episodes of ETS observed were performed in response to an identified clinical need based on changes in a variety of clinical signs and patient behaviour. This study highlights the complex nature of nurses' assessment of the need for ETS and has implications for training and education of nursing staff.
