Chronic ; Intermittent Positive-Pressure Breathing

This patient had received antihypertensive therapy, which was followed by severe acute hypertension (300/260 mmHg), due to inadequate ventilation after anesthesia. Acute hypertensive treatment was performed successfully by lowering blood pressure with chlorpromazine, 25 mg and valium, 10 mg by intravenous injection, with intermittent positive pressure breathing.

BACKGROUND/AIMS: Immediate postpolypectomy bleeding (IPPB) increases the procedure time and it may disturb performing a safe polypectomy. The purpose of this study is to investigate whether clipping before snare polypectomy of large pedunculated polyps is useful for the prevention of IPPB. METHODS: This is a single arm, pilot study. We enrolled patients with pedunculated colorectal polyps that were 1 cm in size or more from 4 university hospitals between June 2009 and June 2010. Clips were applied at the stalk and snare polypectomy was then performed. The complications, including IPPB, were investigated. RESULTS: Fifty six pedunculated polyps in 47 patients (Male:Female=36:11; age, 56+/-11 years) were included. The size of the polyp heads was 17+/-8 mm. Tubular adenoma was most common (57%). The number of clips used before snare polypectomy was 2+/-0.5. The procedure was successful in all cases. IPPB occurred in 2 cases (3.6%), and both of these were managed by additional clipping. Delayed bleeding occurred in another one case (1.8%), which improved with conservative treatment. No perforation occurred. CONCLUSIONS: We suggest that clipping before snare polypectomy of pedunculated polyps may be an easy and effective technique for the prevention of IPPB, and this should be confirmed in large scale, prospective, controlled studies.

A case of Mendelson's syndrome during induction of anesthesia has been reported. The patient was treated with hydrocortisone IV, oxygen c IPPB, aminophylline and antibiotics. The patient recovered completely 3 days after aspiration. We must take the preventive measure for aspiration into the lung during anesthesia, especially obstetric patient.

Post-operative pulmonary complications have been discussed as to causes and preventive methods for a long time. One of these methods is intermittent positive pressure breathing(IPPB) which has been widely advocated, but there are many debates now. We studied the relationship of post-operative pulmonary complications with patient's age, general condition and operation site & duration of IPPB. The results were as follows: 1. The rate of IPPB was 8. 4% of general anesthetic patients. 2. The ratio of medical to surgical patients on in IPPB was 1: 10. 3. We had 13 post-op. pulm. complications with prophylactic IPPB and 4 cases without IPPB. 4. The incidence of post-operative, pulmonary complications increased with the patients age, operative time, number of class in physical status (by ASA) and increased particularly after upper abdominal surgery more than lower abdomen or other sites.

Chronic obstructive pulmonary diseases are being increased every year by many factors. But there are two important factors. First of all the atmospheric contamination is due to modern civilization, secondarily, the increase of old age population which is the result of prolonged life span by contribution of modern medicine. For these reasons increasing chronic obstructive pulmonary disease, anesthesiologists have had increased problems to administer anesthesia, because these patients are most difficult to manage for anesthesia. Author have studied for if it could be diminished these problems by comparing of the complications during period of anesthesia induction, maintenance, recovery and 5 postoperative days, with IPPB therapy and other physical therapy. The results of the study are as follows: 1) Pre and postoperative IPPB therapy is more useful to diminish anesthesia problems compared with other physical therapy. 2) Other physical therapy is useful when compared with controlled group. 3) IPPB therapy is the choice of treatment for postoperative atelectasis. Statistical significance was assessed by using student t test.

The authors have experienced five cases of general anesthesia for repair of diaphragmatic hernia in children, and following results were obtained. Whether it was congenital or traumatic in origin, prompt reduction and repair is desirable if accurate diagnosis was made and patients condition was acceptable, for increased postoperative survival rate and prevention of possible complications. When the intermittent positive pressure breathing was needed during preoperative, intraoperative or postoperative period, the greatest concern of anesthetist is that excessive positive ventilation should be avoid. The most important factors in this situation probably are the use of chest drainage, daily Roentgen-ray examination, and better use of postoperative ventilatory assistance, for prevention of postoperative atelectasis and other pulmonary complications.

OBJECTIVETo evaluate the efficacy of targeted tidal volume ventilation in the treatment of severe neonatal respiratory distress syndrome (RDS).

METHODSEighty-four neonates with severe RDS between June 2008 and January 2010 were randomly assigned to 3 groups according to the ventilation mode: synchronized intermittent positive pressure ventilation plus volume guarantee (SIPPV+VG; n=31), high frequency oscillation ventilation (HFOV; n=23) and intermittent mandatory ventilation (IMV; n=30). The oxygenation status, the durations of oxygen exposure and ventilation and the incidence of complications were observed.

RESULTSThe oxygenation status (P/F and a/APO2) in the SIPPV+VG and the HFOV groups was improved significantly 12 hrs after ventilation (P<0.05). While in the IMV group, the oxygenation status was not improved until 24 hrs after ventilation. The durations of oxygen exposure and ventilation in the SIPPV+VG and the HFOV groups were shorter than in the IMV group (P<0.05). The incidences of air leak syndrome and ventilation-associated pneumonia (VAP) were lower in the SIPPV+VG and the HFOV groups than in the IMV group (P<0.05). The incidence of severe intracranial hemorrhage in the HFOV group was higher than in the other two groups (P<0.05).

CONCLUSIONSCompared with IMV, SIPPV+VG and HFOV can improve the oxygenation status more quickly, shorten the ventilation duration and decrease the incidences of air leak syndrome and VAP in neonates with severe RDS.

Thirty six pediatric patients who were diagnosed as pulmonary atelectasis by chest radiography were managed with one of the following techniques for the treatment of atelectasis: 1) intermittent positive pressure breathing (IPPB) with extrathoracic chest percussion and vibration, 2) IPPB and intrapulmonary percussive ventilation (IPV) and 3) IPV only. Chest X-ray films and arterial pH, Pco, and Po, were obtained for all patients in the morning and the afternoon. And systolic and diastolic blood pressure and heart rate were measured at that time. Alveolar arterial oxygen tension difference was calculated from inspired oxygen fracton and arterial oxygen tension. The rate of treatment of atelectasis was significantly low in the patients with IPPB and chest physiotherpy. But the durations for the treatment were not significantly different among the three groups. There were no significant differences in blood pressures, heart rates and artrial blood gases between pre-treatment and post- treatment states in all groups.

BACKGROUND: It is invasive and accompanies various risks to insert pulmonary artery catheter in order to measure mixed venous oxygen saturation (SvO2) that is associated with patients clinical course and prognosis. If there is relationship between central venous oxygen saturation (ScvO2) and mixed venous oxygen saturation, we can use the central venous oxygen saturation instead of mixed venous oxygen saturation to monitor and treat patients. METHODS: We inserted the Swan-Ganz catheter in 20 patients (male 8, female l2) scheduled for undergoing open heart surgery and accomplished the blood gas analysis of the radial arterial blood, central venous blood and mixed venous blood during postoperative respiratory care in intensive care unit at F1O2 1.0, 0.6 and 0.4 in order. RESULTS: There was no significant difference between central venous blood and mixed venous blood in respect to pH, PCO2, PO2. except the mixed venous blood pH at F1O2 0.6 that is greater than the central venous blood pH at F1O2 0.6. Central venous oxygen saturation and mixed venous saturation were not significantly different and showed the following close relationship: SvO2(%)=15.41+0.80XScvO2 (R=0.88, p<0.05). In respect to the difference according to the variation of F1O2, the SO2 and PO2 at F1O2. 1.0 were higher than the SO2 and PO2 at F1O2 0.6 and 0.4, but the differnce between F1O2 0.6 and 0.4 was not significant. CONCLUSIONS: We might conclude that central venous oxygen saturation might be replaced for the mixed venous oxygen saturation in respiratory care after open heart surgery in adults.
