Alien Emergencies - James White [279]
“…Will you work on the connection to the absorption organ, please,” he ended, “and keep an eye on the monitor.”
Sharing the operative field with the Tralthan, Conway worked quickly and carefully in the restricted space, clamping off the artery beyond the artificial heart connection, detaching it, and reconnecting it to the arterial stub projecting from the replacement organ. Unlike the first, shocking seconds of the earlier hemorrhaging, time seemed to have speeded up. His hands and instruments were well outside the field of the nullifiers, being acted on by four Earth-Gs, so they felt incredibly slow and awkward. Several times his instruments clinked loudly against those of Hossantir. He could sympathize with the surgeon, whoever it had been, who had accidentally knocked that connector valve off its setting. He had to concentrate hard to keep his instruments from leading a life of their own.
He did not watch Hossantir’s work, because the Tralthan knew its stuff and there was no time for surgical sightseeing.
He inserted retaining sutures to hold the artery in position on each end of the connector, which was designed both to hold the ends firmly in position when circulation was restored and to keep the sections of original and replacement tissue apart so as to reduce postoperative rejection problems. There were times when, immunologically speaking, he wondered why a highly evolved and complex organism should be its own worst enemy. Next he began the linkup of the vessel which supplied nutrient from the absorption organ to one of the major heart muscles.
Hossantir had completed its connection and had turned its attention to the minor vessel which supplied one half of the womb when the Hudlar was in female mode—the second, undamaged heart had been performing double duty since the start of the operation. They were short of time, but as yet not dangerously so, when the Tralthan indicated the Monitor with a free appendage.
“Ectopics,” Hossantir said. “One in five, no, one in four. Pressure is reducing. The indications are that the heart will go into fibrillation and arrest very quickly. The defibrillator is ready.”
Conway took a quick look at the visual display where the irregular, ectopic heartbeat broke into the normal rhythm once in every four beats. From experience he knew how soon it could degenerate into a rapid, uncontrollable flutter and, with the subsequent loss of the pumping function, failure. The defibrillator would almost certainly shock it into action again, but that device could not be used while the operation on the replacement heart was in progress. He resumed his work with desperate, careful speed.
So deep was his concentration that all of his minds were becoming involved again, contributing their expertise and at the same time their irritation that it was a set of Earth-human hands which were doing the work and not the assorted manipulators, pincers, and digits of his alter egos. He looked up finally to find that Hossantir and he had finished their connections at the same time. But a few seconds later the other heart went into fibrillation, then arrest. Their time was really short now.
They eased the clamps on the main artery and secondary vessels and watched the flaccid replacement organ swell slowly as it was filled with Forty-three’s blood, checking with their scanners for the formation of air embolisms. There were none, so Conway placed the four tiny
