A prospective, randomized platelet-function study of heparinized oxygenators and cardiotomy suction.

OBJECTIVE: The purpose of this study was to determine if substitution of a heparin-coated oxygenator and salvaged autologous blood for cardiotomy suction would improve platelet function. DESIGN: A prospective, randomized trial. SETTING: A large academic medical center. PARTICIPANTS: Sixty adult patients undergoing coronary artery bypass graft surgery with cardiopulmonary bypass (CPB). INTERVENTIONS: Patients were randomized into 1 of 4 groups in a 2 x 2 factorial design by oxygenator (heparinized v nonheparinized) and blood salvage during CPB (cardiotomy suction v salvaged autologous blood). MEASUREMENTS AND MAIN RESULTS: Primary outcome measures were platelet function, glass-bead retention, platelet dense-body adenosine triphosphate secretion, platelet-rich plasma (PRP) aggregometry, Plateletworks platelet-function analyzer (Helena Laboratories Corp, Allen Park, MI), and platelet count. Secondary outcome measures were chest-tube drainage and allogeneic blood transfusion requirements. All platelet-function tests except thrombin-receptor activator peptide-induced PRP aggregometry showed a reduction in platelet function during and immediately after CPB (all p < 0.05). The only statistically significant difference in platelet-function tests between the groups was the glass-bead assay at 5 minutes before discontinuation of CPB (p < 0.05). This difference resolved 10 minutes after protamine administration. There were no differences between the groups in the amount of blood transfused, chest-tube drainage, and routine laboratory test results. CONCLUSIONS: The authors concluded that the effects of these changes to the CPB circuit were small and inconsequential in this cohort of patients.

Bronchial perforation after closed-tube endotracheal suction.

Iatrogenic bronchial perforation is an uncommon complication in intubated premature infants. The authors present 2 cases of bronchial perforation caused by closed-tube endotracheal suction catheters. These presented in the first 3 days of life with pneumothorax requiring chest tube placement. Medical management was unsuccessful because of the high-volume air leak present and surgical intervention was required. A bronchial perforation of the right lower bronchus was identified in both cases and was repaired in the second case. This represents the first report in the literature of iatrogenic bronchial perforation in premature infants by closed-tube endotracheal suctioning catheters. Bronchial perforation requires early recognition and prompt repair if successful outcome is to be obtained.

Bronchial complication of a closed-tube endotracheal suction catheter.

Iatrogenic bronchial complications in intubated premature infants are rare. The authors present one case of rupture of a closed-tube endotracheal suction catheter. Clinical presentation was a persistent pneumothorax that required chest tube placement in several days. A foreign body was confirmed in x-ray and computed tomography (CT) scan. Flexible bronchoscopy showed a piece of catheter in the left bronchus and using a rigid bronchoscope was possible to remove. No perforation was found. There are a few reports in the literature of iatrogenic bronchial complication in premature infants caused by closed-tube endotracheal suctioning catheters. Endobronchial rupture of this catheter has never been reported.

The addition of an air/water button to a flexible bronchoscope (provided with a suction button) for use as a slim operative panendoscope.

Thin-caliber (4.9 and 6.3 mm) flexible bronchoscopes already provided with a suction button have been modified by adding an air/water button for the control of air insufflation and water irrigation; the channel used is the biopsy-suction one. With the aid of this instrument, several pathologies can be studied and treated, under adverse conditions such as esophageal or recto-sigmoidal stenosis, hematuria in polytraumatic patients, residual stones in patients carrying a T-tube, acute respiratory obstructions, etc.

[Suction-irrigation attachment for the flexible endoscope without integrated operating channel].

BACKGROUND: Endoscopic inspection of the larynx in patients with long-term intubation or patients pharyngolaryngeal injuries is frequently obscured by blood and other secretions. We developed a simple procedure to improve visibility. METHODS: A flexible 4-mm endoscope without an operating channel is inserted into an 18-French suction tube through one branch of a Y-shaped connecting tube (Fig.1). Fluid can be aspirated between the endoscope and the surrounding tube. The site can be flushed in a similar manner. RESULTS: In all examined patients (n = 11) we successfully aspirated fluid (blood/saliva/etc.). CONCLUSIONS: Our proposed suction and irrigation attachment for flexible 4-mm endoscopes without an operating channel permits reliable aspiration under endoscopic inspection, simplifying endoscopic visualization of laryngeal or pharyngeal findings.

[Postoperative wound suction drainage and its effect on wound healing].

The positive as well as the negative effects of wound suction drainage on wound healing are outlined and the inherent physical laws which still were unclear are subject to an experimental analysis. The findings and conclusions which had been determined resulted in a modification of the clinical application practice and evidence points to the up to now daily change of suction bottle by routine as being a significant risk. Contamination of physical conditioned secretion reverse flow while opening the wound drainage system and the proven spreading ability of the bacteria within the drainage tubes leaves the possibility of a postoperative retrograde bacteria contamination reaching up to the wound site. To prophylactically reduce these risks instrumental improvements of the wound drainage system will be presented and discussed.

[Relation of negative pressure difference and artificially elevated intraocular pressure using the suction cup method].

This paper presents regressions and the range of scatter of measured values for current standard ophthalmologic suction cups for the first time. The scatter range is similar to that of blood pressure measurements made by the Riva-Rocci method. Using the regressions presented here it is possible to deduce the increase in pressure from the negative pressure difference in the suction cup; this can be done with sufficient accuracy and the amount of time required is acceptable.

Acceptability of suction curettage and mifepristone abortion in the United States: a prospective comparison study.

OBJECTIVE: We sought to compare the acceptability of suction curettage abortion with that of medical abortion with mifepristone and misoprostol in American women. STUDY DESIGN: We performed a prospective, serially enrolled, cohort analysis. The study population consisted of 152 subjects receiving mifepristone and misoprostol and 174 subjects undergoing suction curettage abortion aged > or =18 years with intrauterine pregnancies of up to 63 days' estimated gestation. Questionnaires regarding expectations and experiences were administered before the abortion and at the 2-week follow-up visit. RESULTS: Subjects undergoing medical abortions reported significantly greater satisfaction than those undergoing surgical abortions (mean rank, 121 vs 149; P <.01) but were no more likely to recommend the method they had just experienced to a friend (97% vs 93.3%). If a future abortion was required, however, 41.7% of subjects undergoing surgical abortions indicated they would opt for a medical abortion, whereas only 8.6% of subjects receiving medical abortions would choose a surgical abortion (P <.001). Failure of the abortion decreased satisfaction in the medical group and increased the likelihood of choosing a surgical abortion for a subsequent procedure (P <.001). Surgical subjects who experienced more anxiety than expected during the abortion were more likely to choose a medical procedure for a subsequent abortion (P <.01). CONCLUSION: Women receiving mifepristone and misoprostol were more satisfied with their method and more likely to choose the same method again than were subjects undergoing surgical abortion. Failure of a medical abortion and increased anxiety during surgical abortion were associated with preference for the alternative technique in a future procedure.

Suction drainage culture as a guide to effectively treat musculoskeletal infection.

Following surgery for musculoskeletal infection, a positive suction drainage culture (SDC) is consistent with persistent sepsis. Our objective was to determine the effect of a negative SDC obtained in subsequent operations on the outcome of a musculoskeletal infection. 99 patients were prospectively enrolled, all treated surgically for musculoskeletal infection utilizing suction drainage and appropriate antimicrobial therapy. Surgery consisted of irrigation, debridement, and prosthetic exchange or implant removal. SDC was considered negative if all bottles resulted in negative cultures. Following SDC results, patients were placed into 1 of 2 treatment groups: 1) Negative SDC, and no new operation; or 2) Positive SDC, and new operation(s) until SDC was negative. Antibiotic therapy ranged from 6-12 weeks (osteomyelitis) to 10-21 d (soft tissue). Both groups were similar with regard to baseline characteristics. Cure was obtained in 91.8% of patients (56/61) in group 1 and 91.6% of patients (22/24) in group 2. Similar results were obtained in patients with an infection in the presence of an implant. In conclusion, a negative SDC following surgery for a musculoskeletal infection is a strong indication of eventual outcome.

Risk of hepatitis B virus transmission via dental handpieces and evaluation of an anti-suction device for prevention of transmission.

We evaluated the risk of hepatitis B virus (HBV) transmission via dental handpieces and the effects of an anti-suction device in preventing HBV contamination. The results of our study show that under certain conditions, HBV transmission can occur when an anti-suction device is used during dental procedures. We conclude that such devices may decrease contamination, but do not eliminate it.

Evaluation of routine tracheal extubation in children: inflating or suctioning technique?

We studied prospectively the effects of the technique of tracheal extubation on arterial haemoglobin oxygen saturation (SpO2) in 120 ASA I-III children, mean age 5.3 (range 0.25-16.9) yr. At completion of surgery, tracheal extubation was performed when spontaneous ventilation had resumed, children were fully awake and SpO2 was 99-100%. Children were allocated randomly to receive a single lung inflation manoeuvre with 100% oxygen before tracheal extubation (group I; n = 59) or to have the tracheal tube removed while applying suction through the tube (group S; n = 61). SpO2 was monitored during the first 5 min after tracheal extubation in the operating room. Supplementary oxygen was given if SpO2 decreased to less than 92%. The time between tracheal extubation and decrease in SpO2 to 92% (T92) was recorded. Children in group S required oxygen administration more frequently after tracheal extubation than those in group I (65.6% vs 45.8%; P = 0.04), and had a three-fold shortening of T92 (mean 25 (SD 19) s vs 85 (63) s; P = 0.0001). These effects were more pronounced in children less than 4 yr of age compared with older children. We conclude that tracheal extubation greatly impaired oxygenation and therefore administration of oxygen was appropriate. This impairment was more marked when suction was used, and in young children. Lung inflation with 100% oxygen before removal of the tracheal tube is advised before routine tracheal extubation in children.

Retrieval of a retrograde catheter using suction, in patients who cannot open their mouths.

In difficulty, tracheal intubation can be facilitated by passing a retrograde catheter, but the mouth has to be opened for the retrieval of the catheter from the pharynx. Two patients with ankylosis of a temporomandibular joint were unable to open their mouth, and required general anaesthesia for gap arthroplasty. Because we did not have a flexible fibreoptic laryngoscope, we used a suction catheter to retrieve an epidural catheter from the pharyngeal cavity, which had been passed retrogradely from a cricothyroid puncture. Catheter-guided tracheal intubation was done without complication. A suction catheter can assist retrograde retrieval of a catheter to aid intubation in patients who cannot open the mouth.

Suction lipectomy--a review of 200 patients over a six-year period and a study of the technique in cadavers.

Suction lipectomy is designed to reduce subcutaneous fat. It is strictly a procedure for the removal of localized fat and body contouring in selected patients and is not a substitute for weight reduction. The technique and the complications associated with the procedure were reviewed in more than 200 patients. Suction lipectomy was performed on fresh cadavers to study the nature of the fibrous tissue and to better understand why the procedure has proved safe.

Routine use of a suction drain in facial rhytidoplasty.

The effectiveness of a suction drain in facial rhytidoplasty was evaluated in 46 women ranging in age from 41 to 78 years. The drain was placed on the left side of the face in 16 and on the right in 14, and no drain was used in 16 patients. The drain was removed in 24 hours regardless of the amount aspirated, which varied between 0 and 25 ml, with an average of 7.8 ml. Although none of these patients developed a hematoma while the drain was in place, a hematoma did occur in 1 patient on the drain side following its removal. Despite the variable quantities of fluid aspirated, there was no clinical difference in swelling noted around the face and neck area when the two sides were compared. Similarly, one could not distinguish this group of patients from those 16 who did not receive the drain. The routine use of continuous suction drains for patients undergoing rhytidoplasty is therefore probably unnecessary.

Treatment of bilateral axillary hyperhidrosis by suction-assisted lipolysis technique.

Axillary hyperhidrosis, although not life-threatening, is a troublesome condition which produces a personal and social handicap of great significance to patients for many years before they seek a cure. Treatment has consisted of application of topical antiperspirants, systemic anticholinergic medications, excision and primary closure of the involved axillary skin, subdermal shaving of the subcutaneous fat pad containing the hypersecreting sweat glands, and combinations of all of the above. Medical treatment is frequently inadequate and surgical techniques so far described may carry significant morbidity. We have used the technique of suction-assisted lipolysis as an alternative method of treatment for this condition. The procedure has been employed successfully in one patient with no recurrence after one year of follow-up. The operation is done as an outpatient procedure under general or local anesthesia. Suction is carried out through a 1-cm incision in the anterior axillary fold and the entire surface of the dermis is fully "vacuumed" in all directions with 15 to 20 strokes, using a 5- or 7-mm diameter cannula. The area treated includes the area of maximal axillary hair growth and 5 to 6 cm beyond. Routine dressings are removed five days posteroperatively, with the patient generally resuming all activities within one week.

Fatal necrotizing fasciitis following suction-assisted lipectomy.

Forty-eight hours following extensive blunt suction lipectomy with 3,000 cc of tissue removed, a 36-year-old woman presented to an emergency room with necrotizing fasciitis of both lower extremities extending over the buttock and to the lower third of the back. Tissue cultures and blood culture grew out a pure culture of beta-hemolytic streptococci. The patient rapidly progressed into a comatose state and, despite extensive debridement and appropriate antibiotic therapy, in addition to hyperbaric oxygen treatments, she died on day 9 of her hospitalization (day 11 following the suction lipectomy). To our knowledge this is the first published mortality reported in the United States following this procedure.

The use of suction curettage as adjunct to the management of lymphedema.

This case report describes the use of suction curettage as an adjunct to the method of skin and subcutaneous tissue excision in the treatment of primary lymphedema. Pretreatment with high-vacuum cannula suction can provide three advantages over straightforward primary excision and closure; (1) larger volumes of skin and subcutaneous tissue can be resected at a single setting; (2) tensionless closure can be obtained without skin flap undermining; and (3) procedural blood loss is minimized.
