Fistulizing reoperations in open-angle glaucoma

The authors analyze the results of repeated fistulization surgery (traditional trabeculectomy and that combined with resection of the episclera, and valvular trabeculectomy) in 40 patients (41 eyes) with primary open-angle glaucoma. A follow-up of 6 mos to 4 yrs has shown normalization of the ophthalmic tone in 90.2% of cases, in 65.8% of these this was achieved without drugs. Vision acuity remained unchanged or improved in 58.5% of cases, visual field was preserved or improved in 80.5% of patients. These results have lead the authors to a conclusion that a stable hypotensive effect can be achieved if repeated fistulization is performed outside the site of the primary intervention. If repeated trabeculectomy has to be performed at the site of the primary intervention, it is recommended to be combined with resection of the episclera, this improving the reliability of the hypotensive effect of surgery.     

Assistor for direct mechanical heart massage

Conclusions 1. Direct mechanical heart massage using the assistor can maintain in a stable manner for a prolonged period both the frequency and the constrictive force, and can also regulate the durations of the systolic and diastolic phases. 2. Direct mechanical heart massage is an effective method of restoring blood circulation when employed immediately after a sudden heart stoppage as well as after a lapse of 10 minutes. 3. The increased pressure in the left auricle during heart massage indicates the deficiency of the left ventricle and is apparently one of the basic causes that limit the duration of effective blood circulation.

Maintenance of the circulation and the restoration of heart function in the donor body by means of direct mechanical heart massage for subsequent transplantation (an experimental study)]

The possibility of maintenance of circulation and subsequent restoration of the function of the heart in the organism of the donor, after 10-minute arrest of circulation, for transplantation of the heart was investigated. Study of the hemodynamic, biochemical, metabolic, and structural changes in the myocardium after 2-hour mechanical massage without and with pharmacological protection of the myocardium (glucose--insulin--potassium, hydrocortisone, dipyridamole), without and with restoration of cardiac activity in the organism of the donor and the recipient after transplantation of the second heart by the method suggested by Moory et al. in artificially created left ventricular insufficiency showed that direct mechanical massage of the heart may be used for its short-term preservation in the donor organism.     

Complex prevention of suture incompetence of the duodenal stump

The work has determined the directions--both surgical and conservative--of complex prophylactics of incompetence of duodenal stump sutures. The following measures can be used in order to solve the task: draining operations of the duodenum, Billroth-I resection of the stomach, resection for the exclusion and use of early probe enteral nutrition in the postoperative period.     

Results of medical research carried out in 1985 on prolonged space flights

This paper presents medical results obtained during the fourth expedition of five cosmonauts onboard orbital complexes Salyut-7--Soyuz-T-13 and Salyut-7--Soyuz-T-14. The cardiovascular system was examined using 36 resting and provocative tests. They were performed by means of electrocardiography, tetrapolar rheography, arteriovenous pulsography and tachooscillography. In addition, body mass and leg volume were measured. The above parameters showed typical variations as well as individual changes related to the preflight circulation level and environmental effects. The use of modified regimens of provocative tests demonstrated their applicability to the assessment of the cardiovascular function in space flight.
