[Hemostasis in the nose with bipolar suction and a coagulation probe under endoscopic control].

To stop nasal bleeding we use a manually operated combined bipolar suction and coagulation instrument under microscopic or endoscopic control, managed by one hand. As a result of the simultaneous suctioning of blood, the bleeding source can be coagulated even during the most effussive bleeding. Since the instrument is a combination of suction tube and bipolar coagulation sound, it can perform three functions at the same time: inspection of the source of bleeding, sucking off the blood, and coagulation. This does away with the need of nasal tamponade which most patients find highly disagreable.

Modified suction system for neurosurgery.

A new system providing suction for neurosurgical operations is presented. It is designed so that the amount of suction is readily controllable and provides adequate suction for the removal of fluid and blood clots without damage to the nervous tissue. The device also allows the surgeon an unrestricted view of the operative field.

[Laryngoscope with suction tube (author's transl)].

A laryngoscope blade with an integrated suction tube is described. Suction and laryngoscope can be handled simultaneously by one hand. The suction guarantees a free sight during intubation in cases of bleeding in the nasopharyngeal region and may also prevent the aspiration of acid gastric contents.

A new instrument for closed irrigation-suction treatment.

Orthopedic surgeons are often faced with the surgical complication of fulminating deep wound infection and bone and joint infection after complicated fractures. Two hundred and seventy patients were treated for bone and joint infection by closed irrigation-suction from 1970 to 1982. Obstruction of the drainage tube, solution leakage, and post-operative bleeding were the knotty problems. Our new instrument for irrigation-suction treatment resolved these problems. The instruments consists of a suction pump, a channel changer, and a double tube system.

Evaluation of the negative pressure suction method in the cytodiagnosis of nasopharyngeal carcinoma.

A special device for collecting exfoliative cells in nasopharyngeal carcinoma diagnosis by negative pressure suction method is recommended. This device consists of a metallic suction tube with a round tip and a modulator which is connected to a suction pump; it passes via the oral cavity into the nasopharynx to collect exfoliative cells. From March 1973 to July 1977, 824 out-patients were examined with cytology and biopsy in our hospital. Of these, 481 cases were confirmed as nasopharyngeal carcinoma. Among them, 431 were cytology-positive; 453 cases were biopsy-positive. The positive cytology rate was 89.6% and the positive biopsy rate was 94.2%.

[A non-invasive portable blood-glucose monitoring system: sampling of suction effusion fluid].

We developed a new portable transcutaneous blood glucose monitoring system using non-invasive collection of suction effusion fluid (SEF) from human skin. A ion sensitive field effect transistor (ISFET) sensor was employed to measure glucose concentration in a very small quantity of the SEF. The system was composed of a couple of portions. One structure was a suction cell, and the other was a main frame. The suction cell included the ISFET glucose sensor, a dilution mechanism, and a sucking interface to human skin. The main frame contained a dilution solution reservoir, a liquid waste reservoir, a fluid pump, a vacuum pump, a micro processor, batteries, and a user interface. The system is self-contained for portable usage during up to 6 hrs monitoring. This system may be the first blood glucose monitoring equipment which does not use blood sampling.

Intraoperative suction catheter tip contamination.

Suction catheter tip contamination is a potential source of intraoperative inoculation of wounds with bacteria. The continuous passage of large quantities of air through a blood-soaked catheter tip during the course of surgical procedures can lead to significant contamination. This in turn may contribute to late wound infection due to inoculation of the deeper recesses of the wound via the contaminated suction catheter tip. We have conducted a prospective clinical study to confirm the incidence of suction catheter tip contamination during orthopaedic trauma surgery and propose changes to current practice to reduce the incidence.

Effect of oxygen insufflation during endotracheal suctioning on arterial pressure and oxygenation in coronary artery bypass graft patients.

BACKGROUND Numerous studies have demonstrated the need for increased inspired oxygen with endotracheal suctioning to prevent hypoxemia; however, increased arterial pressure has been reported as a consequence of lung hyperinflation/inflation used to deliver hyperoxygenation. OBJECTIVES To compare insufflation during endotracheal suctioning with a standard procedure of hyperoxygenation using a ventilator on arterial pressure, pulmonary artery pressure, heart rate, arterial oxygen saturation, and blood gases in intubated, mechanically ventilated coronary artery bypass graft patients. METHODS A within-subjects, repeated-measures design was used to measure arterial pressure (systolic, diastolic, and mean), pulmonary artery pressure (systolic, diastolic, and mean), airway pressure, heart rate and rhythm, arterial oxygen tension, arterial carbon dioxide tension, pH, and arterial oxygen saturation during an oxygen insufflation protocol and a hyperoxygenation protocol via the ventilator. RESULTS Using analysis of variance for repeated measures, statistically significant time effects were found for all variables. Statistically significant differences between protocols over time were found for arterial pressure, arterial oxygen tension, and arterial oxygen saturation. CONCLUSIONS Oxygen insufflation resulted in less increase in arterial pressure than did the hyperoxygenation protocol. The hyperoxygenation protocol resulted in hyperoxia. Based on this study, oxygen insufflation is a safe alternative for providing oxygen during endotracheal suctioning.

Performance of indirect embolectomy aided by a new developed flush-suction catheter system. Forty-seven experimental embolectomy procedures in test animals.

Embolectomy by means of the Fogarty catheter is the therapy of choice in the event of acute occlusions of limb arteries. However, less invasive catheter procedures have become established means to perform embolectomies lately. In order to improve the results after using the above mentioned methods, we have developed a new embolectomy procedure. The system applied consists of a flush-suction catheter as well as a high pressure pump. There is a jet-suction unit on the head of the tubular two-lumen catheter to gather thromboembolic material from the circumference of the head, to erode the collected material and evacuate it. The flushing pressure is generated by the pump. For the experimental testing of the system, the flush-suction embolectomy has been performed in 19 pigs after 47 artificial produced extremities embolism. Angiographically and angioscopically it could be proved that even older thrombotic material could be removed completely and without significant trauma of the vessel. At the pathologic investigation of the vessel in which embolectomy had been performed in no case an essential vessel-wall damage could be found. In almost each case the embolic material was removed completely. Only in 5 cases (10.6%) we have distal microembolism. Due to the experimental tests, the system turns out to be reliable as far as the technique is concerned. In addition, in the event of clinical application, the system allows the expectation of a reduction of the time interval between diagnosis and therapy, as well as a percutaneous application.

Reduction mammaplasty by suction alone.

Because unsatisfactory scars often result when traditional methods of reduction mammaplasty are performed, techniques that leave less noticeable scars have been advocated recently. One such technique is suction lipectomy, which has been employed previously, but only for patients who have well-located, small nipple-areola complexes and whose hypertrophy is primarily fat. I have found that concern for the size and location of the nipple-areola complex and cause of hypertrophy are unfounded. Thus reduction mammaplasty by suction alone may be the technique of choice in certain patients. Eleven patients had reduction mammaplasty by suction alone and obtained aesthetically pleasing breasts that had good sensation and minimal scars. As a result, the method is suggested for selected patients: those with minimal to moderately large breasts.

[Newly developed vacuum suction valve for microsurgery].

A vacuum operated suction appliance can be invaluable for all areas of surgery. The suction process carries a greater risk (e.g. dizziness, deafness), especially in microsurgery of the ear. A newly developed vacuum valve for microsurgery that is mechanically adjustable is presented. The surgeon operates the valve with his foot outside the aseptic area of surgery. The valve enables him to regulate the vacuum or to quickly interrupt the suction process. This allows for swifter, safer surgery. Examples of use of the device in microsurgery of the ear are described in detail.

Direct tracheobronchial suction for massive post-extubation atelectasis in premature infants.

UNLABELLED: A prospective four-year study was done in a neonatal intensive care unit (NICU) to evaluate a technique, called direct tracheobronchial suction (DTBS), for rapidly removal of obstructive secretions from the tracheobronchial tree in newborn infants with massive post-extubation atelectasis (PEA). Selected cases who met the following criteria were enrolled: 1) developing new massive atelectasis within 48 hours after extubation; 2) no response to vigorous chest physiotherapy(CPT) and continuous deterioration; and 3) no air-bronchogram in the atelectatic lung field. DTBS was carried on at bedside by direct insertion a 6.5 Fr suction catheter into tracheobronchial tree and suctioning. Clinical and laboratory assessments were made in each case prior to and at two hours after DTBS for comparison. A total of 145 (19.7%, 145/736)) PEA occurred in a consecutive 736 postextubated newborn infants. Thirty-one atelectasis (4.2%, 31/736) that developed in 18 infants were managed with DTBS. There was a significant higher incidence of PEA developed, as well as a higher ratio of PEA been treated by DTBS, in the group of body weight < 1,500 g than the group of > or = 1,500 g. All except one infants weighed less than 1,500 g, with a mean of 1,043 +/- 269 g. Sixteen infants had been intubated for more than seven days with a mean of 14.1 +/- 5.0 days. Nine infants required more than one session of DTBS. DTBS was quite effective in immediate removal of retained secretions and improvement of pulmonary condition. By clinical assessment, respiratory distress improved with increased audible air entry on the affected lung, decreased chest retractions, and a significant fall in respiratory rate and heart rate. Arterial blood gases analysis showed significant improvement of pH, partial pressure of carbon dioxide and oxygenation ratio. By chest radiograph, DTBS resulted partial or nearly complete resolution of the atelectasis in all cases. DTBS procedures were well tolerated by all infants without significant sequelae. CONCLUSION: This study suggests that DTBS is a simple and effective therapeutic modality to rapidly correct the massive PEA which resist to vigorous CPT in small infants.

Suction cup/contact lens complications following penetrating keratoplasty.

PURPOSE: Rigid gas permeable (RGP) contact lenses facilitate visual rehabilitation in cases of high or irregular corneal astigmatism following penetrating keratoplasty. A variety of plunger-like suction cup devices are available to assist in the removal of these lenses. METHODS: We report three patients with serious complications associated with the use of a suction cup device for contact lens removal following penetrating keratoplasty. RESULTS: Two patients suffered corneal wound dehiscence following contact lens removal; one contact lens was removed by the patient's spouse and the other was removed by a trained technician. A third patient triggered a graft rejection, and ultimately, graft failure, after a vigorous attempt at lens removal. CONCLUSIONS: Forces generated by suction cup devices during removal of RGP contact lenses are sufficient to cause significant trauma. Contact lenses with an apical clearance fit may augment these forces, with the potential for complications following penetrating keratoplasty.

Endotracheal suctioning.

Endotracheal suction is one of the most common procedures carried out in an intensive care unit. Review of the evidence reveals that both manual hyperinflation and the instillation of saline are not effective and are potentially harmful. The frequency of suctioning, catheter-size, suction pressure and open versus closed systems are discussed. Recommendations for practice are outlined.

[Physical forces in blister formation. I. Direct measurement of blister fluid colloid osmotic pressure in suction blisters and in bullous diseases (author's transl)].

The physical forces operative in the fluid migration from the interstitial spaces into the blister cleft have not been directly measured until now. The colloid osmotic pressure was determined in suction blister fluid after mild suction blister production by a modified "Dermovac" and in blister fluid of patients with dermatitis herpetiformis, bullous allergic contact dermatitis and pemphrigus vulgaris and in the sera of healthy persons. The colloid osmotic pressure was measured by means of a recently developed osmometer with a semipermeable membrane between two chambers, one of them filled with Ringer solution, the other with the blister fluid sample. The negative pressure in the first chamber was determined. The colloid osmotic pressure of suction blister fluid averages approximately 7 cm H2O, the values reach about 20 cm H2O in bullous diseases and about 38 cm H2O in the normal sera. The blister fluid colloid osmotic pressure has to rise to about 15 cm H2O or more to cause the fluid transport from the interstitial spaces of the surrounding tissue into the blister because of the negative interstitial fluid pressure and the colloid osmotic pressure of the interstitial fluid. Otherwise the blister fluid is reabsorbed back into the interstitial spaces.

Influenced of food on the kinetics of 8-methoxypsoralen in serum and suction blister fluid in psoriatic patients.

The influence of food on the kinetics of 8-methoxypsoralen (8-MOP) in serum and suction blister fluid was evaluated in a cross-over study in 19 psoriatic patients under PUVA treatment. The peak serum concentration of 8-MOP was reached 1.5 h after ingestion on an empty stomach, and in suction blister fluid the maximum concentration was already present in the first sample taken after 2 h, the time when UVA radiation was given. The postprandial kinetics of 8-MOP in serum and suction blister fluid differed, the highest levels being reached, respectively, at 2.4 and 3 h after intake, i.e. in both body fluids after irradiation had started. The side effects of 8-MOP, such as nausea and dizziness, in the two groups were similar. The present results indicate that to optimize the therapeutic effect of PUVA in individual patients, 8-MOP should be given on an empty stomach.

Suction-assisted lipectomy in the older patient.

A retrospective study of 158 suction-assisted lipectomy patients ranging in age from 50 to 81 years was completed in order to determine the success of the technique in this subset of older patients. These were primarily cosmetic procedures of the trunk and extremities. The patients presented with a typical wide spectrum of systemic medical disorders as one would expect in this age group. The study revealed no mortalities and limited suboptimal aesthetic results consisting of insufficient fat removal, requiring secondary suctioning, and waviness or asymmetry. We feel that with adequate preoperative explanation and planning suction-assisted lipectomy can be a rewarding procedure in patients of all ages.

Bronchial electrocardiography to determine left or right main bronchial placement of an endotracheal suction catheter tip.

OBJECTIVE: To assess the utility of a blue lined angle tipped and electrode tipped catheter, to guide left and right main bronchus cannulation. DESIGN: A prospective study. SETTING: An 11-bed general intensive care unit in a 900-bed teaching hospital. PATIENTS: 50 intubated intensive care patients, in sinus rhythm with normal P and QRS mean frontal axis, who required endobronchial suctioning for routine respiratory management. INTERVENTIONS: Endobronchial electrocardiography was used to position a blue lined angle tipped and electrode tipped suction catheter into the right and left main bronchi. RESULTS: Selective cannulation of the left main bronchi was determined by observing a biphasic or inverted P wave in 42 patients, or biphasic or inverted QRS complex in 31 patients. In 8 patients in whom no changes in the ECG were found, bronchoscopic placement of an ECG electrode into the left main bronchus demonstrated a biphasic or inverted P wave in 8 patients and a biphasic QRS complex in 3 patients, confirming the failure to cannulate the left main bronchus in these 8 patients. CONCLUSIONS: Using a blue lined, angle tipped and electrode tipped catheter for endotracheal suctioning, endobronchial electrocardiography may be a simple method to signal left or right main bronchus cannulation.
