They clustered around the patient like a shoal of ungainly fish, Conway thought, about to begin their surgical nibbling.
“The rear limbs have escaped with superficial damage and will heal naturally,” Yarrence said, more for the benefit of his recorders than for Conway. “The two midlimbs and left forelimb have been lost, and the stumps will require surgical trimming and capping in preparation for the fitting of prosthetics. The right forelimb is still attached but has been so badly crushed that in spite of efforts to reestablish circulation to the affected areas, necrosis has taken place. This limb will also require removal and capping. .
The FROB in his mind stirred restively and seemed to be raising objections, but Conway did not speak because he had no clear idea of what it was objecting to.
Of the stump,” the Kelgian Senior went on. “There is a metal splinter which has been driven into the right thoracic area with associated damage to a major vein, the bleeding from which has been incompletely controlled by the application of external pressure. This situation must be rectified urgently. There is also cranial damage, a large depressed fracture which is compressing the main nerve trunk and affecting mobility in the rear limbs. Subject to approval”. . . Yarrence glanced briefly in Conway’s direction we shall remove the damaged forelimb, which will allow easier access for the teammembers working in the cranial area, and prepare the stumps for-”
“No,” Conway said firmly. He could not see anything but the Kelgian’s conical head inside the heavy protective garment, but he could imagine the silvery fur tufting in anger as he went on. Do not cap the forelimb stumps, but prepare them instead for a transfer and transplant of the rear limbs. Otherwise your procedure as outlined is approved.”
“The risk to the patient is increased,” Yarrence said sharply, “and the operational time will be extended by at least twenty percent. Is this desirable?”
Conway was silent for a moment, thinking about the quality of life of the patient following the success of the simple as opposed to the more complex operation. Compared with the immensely strong and precisely controlled forelimbs possessed by a normal FROB, the telescoping, hinged, and swiveling prosthetic was ridiculously weak and inefficient. As well, Hudlar amputees found them aesthetically displeasing and distressing when the forelimbs-which were the members most conveniently placed to the eyes and used for the more delicate physical manipulations, including the long and involved preliminaries to mating-were artificial. Transplanting the rear limbs forward, although risky considering the weakened state of the patient, was infinitely preferable, because if the operation were successful, it would provide the FROB with forelimbs which would be only fractionally less sensitive and precise than the originals. Since the limbs would be coming from the same entity, there would be no immune system involvement or tissue rejection problems.
The Hudlar material in Conway’s mind was insisting that he disregard the risks, while his own mind was trying desperately to find ways of reducing them.
He said, “Leave the forelimb transplant until the cranial and abdominal work is successfully completed; otherwise the transplant would be wasted effort. Don’t forget to clean the tegument frequently and respray with anesthetic. In cases like this the absorption mechanism is affected by the general condition of-”
“I know that,” Yarrence said.
“Of course you do,” Conway went on. “You have the Hudlar tape, too, probably the same one as I have. The operation carries a strong element of risk, but it is well within your capabilities, and if the patient were conscious I have no doubt that-”
“It would want to take the risk, too,” Yarrence broke in again. “But if the Hudlar in my mind feels that way, I, as the surgeon, feel obliged to express caution on its behalf. But I agree, Conway, the operation is desirable.”
Conway detached himself from the operating frame, paying Yarrence the compliment of not watching the opening stages of the operation. In any case, incising an FROB’s ultratough tegument required the tools of an engineering workshop rather than an operating theater, because the cauterization effects of using fine laser cutters, which were so necessary during internal surgery, seriously inhibited healing along the faces of tegument incisions. The blades which had to be used were two-handed Kelgian Six scalpels, and they required a lot of physical effort as well as a high degree of mental concentration in use, and frequently the medic was in greater danger from the blade than the patient. It was a good time to remove all unnecessary distractions from Yarrence, which included the presence of a would-be Diagnostician, and move to FROB-Ten.
