[Changes in the coagulation properties of tissues of the chest cavity and bronchial stump after the removal of a lung]. / Izmeneniia koaguliatsionnykh svoistv tkanei grudnoi kletki i kul'ti bronkha posle udaleniia legkogo.

Experiments in dogs have shown that ablation of one lung is followed by increased coagulative activity and decreased fibrinolytic activity of tissues of the thoracic cavity, devoid of pleura which is responsible for better formation of coagulated hemo-and fibrinothorax. The balloon pleural obturator is shown to change coagulative properties of the tissues thus preventing blood coagulation and fibrin formation. Bringing of fibrin to the bronchus stump contributes to hermetization of the bronchus stump.

A new endoillumination infusion cannula for pars plana vitrectomy.

A new endoillumination infusion cannula has been developed that allows for wide field illumination of the retina during pars plana vitrectomy surgery. This frees the surgeon from having to use one of the intravitreal probes for endoillumination when using the bimanual technique in pars plana vitrectomy. This innovative endoillumination source also can be used with indirect ophthalmoscopy, at surgery, avoiding the glare generated by the indirect ophthalmoscope's light beam interacting with the corneal surface and the condensing lens surfaces.

An improved endoillumination probe for pars plana vitrectomy.

A newly modified endoillumination probe using the Ocutome handle has been developed that has 2.5 times more total light output and over four times more light intensity than the conventional endoillumination probe. The new probe is particularly useful in situations where there is extremely dense vitreous hemorrhage and when one requires additional light for 16-mm cinematography.

A fixed contact lens retaining ring with its own irrigating system for pars plana vitrectomy.

A fixed contact lens retaining ring with its own irrigation system is described for use in pars plana vitrectomy. The advantages and disadvantages of this system are compared with the hand-held contact lens instruments.

[Use of pleural obturator after pneumonectomy]. / Primenenie plevroobturatora posle pul'monektomii

The authors suggested and employed in 34 patients a balloon-devise, that is inflated in the pleural cavity following a removal of the lung. This lessens plasma and hemorrhages, thus contributing to the prophylaxis of postoperative empyemas.
