Ambulance Ship sg-4

by James White

  Although large, the room was overcrowded-mostly with people who had no business being there and no reason other than professional curiosity. Conway could see one of the scaly, membranous Illensan PVSJs, its loose protective suit transparent except for the faint yellow fog of chlorine it contained, and there was even a TLTU encased in a pressure sphere mounted on caterpillar tracks, which was the only way a being who breathed superheated steam at high pressure could associate professionally with patients and colleagues with less exotic metabolisms. The remainder were warmblooded oxygen-breathers-Melfans, Kelgians, Nidians and one Hudlar-with one thing in common besides their curiosity: the gold or gold-edged ID badges of Diagnosticians or senior physicians.

  Rarely had Conway seen so much medical talent concentrated in such a small area.

  They all stayed well clear of the transfer team as the patient was moved from the litter onto the examination table, supervised by Thornnastor itself. The litter was left unsealed and moved back to the ward entrance so as to be out of the way; then everyone began edging closer.

  Murchison and Naydrad were watching on the Rhabwar’s screen, Conway knew, as Thornnastor began the preliminary examination, which was in all respects identical to the one carried out by Murchison and Conway on the ambulance ship-a careful check of the vital signs, even though at this stage nobody could be quite sure what was or was not a normal pulse, respiration or blood pressure reading for a DBPK-followed by deep and detailed scanning and gentle probing for physical injury or deformation. While it worked, Thornnastor described in detail everything it did, saw or deduced for the many medics who were observing on the teaching channels. Occasionally it paused to ask questions of Murchison on the ambulance ship or of Conway in the ward regarding the patient’s condition immediately following its rescue, and for any comments that might be helpful.

  Thornnastor had reached its unrivaled eminence in e-t pathology by asking questions and pondering the answers, not by listening to itself pontificate.

  Finally, Thornnastor’s examination was complete. It brought its massive body fully erect so that the osseous dome housing its brain was almost hidden by the curves of its massive triple shoulders. Its four extensible eyes regarded, simultaneously, the patient, the medics ranged around the examination table and the vision pickups through which the Rhabwar and the other non-present observers were viewing the proceedings. Then it spoke.

  The most serious damage had been sustained by the patient’s lungs, where decompression effects had ruptured tissue and caused widespread bleeding. Thornnastor proposed relieving this situation by withdrawing the unwanted fluid via a minor surgical intervention through the pleural cavity and into the trachea for the purpose of assisting the patient’s breathing by positive pressure ventilation of the lungs with pure oxygen. There was a wide range of tissueregenerative medication available for warm-blooded oxygenbreathers, but the tests that would be carried out on the DBPK cadavers to find one harmless to the DBPK species would be exhaustive and would require two days at least, by which time a safe anesthetic would also be available. Without immediate surgical intervention the patient would not live for more than a few hours. Neither of the proposed procedures was lengthy, the associated pain was minimal, and as Prilicla reported, the patient was too deeply unconscious to be aware of pain, so Thornnastor, assisted by a Melfan senior physician and a Kelgian theater nurse, would operate at once.

  Considering the condition of the patient, Conway thought, it was the only sensible thing to do. He felt irked that it was not himself who was assisting Thornnastor, since he had had prior experience with the DBPK life-form. But then he realized, from listening to the respectful whispers coming from the other observers, that the Melfan senior assisting was Edanelt, one of the hospital’s top e-t surgeons, the permanent possessor of four Educator tapes, and according to the grapevine, a being shortly to be elevated to Diagnostician status. If a surgeon of Edanelt’s eminence could be big enough to assist, then Conway should be able to watch without radiating too much envy.

  It had never ceased to amaze Conway, despite the hundreds of operations he had seen Tralthans perform, that such a monstrous and physically ungainly species could produce the Federation’s finest surgeons. The DBPK patient did not know how fortunate it was, because it was said in the hospital that no life-form, no matter how hopeless its case might be, was ever lost if it came under Thornnastor’s personal care. Such a thing was unthinkable, Thornnastor was reputed to have said, because it was not in its contract …

  “Consciousness is returning,” Prilicla announced suddenly, barely ten minutes after the operation was complete. “It is returning very rapidly.”

  Thornnastor made a loud, untranslatable sound, which probably signified satisfaction and pleasure. “Such a rapid response to treatment promises a favorable prognosis and, I should think, an early recovery. But let us withdraw for a short distance. Even though a member of a star-traveling race is accustomed to seeing other lifeforms, in its weakened state our patient might be worried by the close proximity of a group of such large and diverse beings as ourselves. You agree, Doctor Prilicla?”

  But the little empath did not have a chance to reply, because the patient had opened its eyes and was struggling so violently against the body restraints that its tracheal air hose threatened to become detached.

  Instinctively, Thornnastor reached over the patient to steady the air hose, and the DBPK became even more agitated. The emotionsensitive Prilicla began trembling so violently that it was in danger of coming unstuck from the ceiling. Suddenly the patient stiffened and remained absolutely still for several minutes, but then it began to relax again as the Cinrusskin radiated sympathy and reassurance.

  “Thank you, Doctor Prilicla,” said Thornnastor. “When communication has been established, I shall apologize to this patient for nearly frightening it to death. In the meantime, try to let it know that we wish it well.”

  “Of course, friend Thornnastor. It is feeling concern now, rather than terror, and it seems to be deeply worried about something which Prilicla broke off and began to tremble violently.

  What happened next was utterly impossible.

  Thornnastor began to sway alarmingly on its six stubby legs, legs which normally gave the Tralthan species such a stable base that they frequently went to sleep standing up; then it toppled onto its side with a crash that overloaded the sound pickup on Conway’s suit. A few yards away from the treatment table the Melfan Edanelt, who had been assisting Thornnastor, collapsed slowly to the floor, its six multijointed legs becoming progressively more limp until the underside of its exoskeletal body hit the floor with a loud click. The Kelgian theater nurse had also slipped to the floor, the silvery fur on its long, cylindrical body undulating and puckering as if being affected by a tiny whirlwind. A member of the transfer team standing beside Conway dropped loosely to his hands and knees, crawled for a short distance along the floor and then rolled onto his side. Too many e-ts began speaking at once, and Earth-humans trying to outshout them, for Conway’s translator to produce anything intelligible.

  “This can’t be happening he began incredulously.

  Murchison’s voice sounded in his helmet phones, speaking on the ship frequency. “Three extraterrestrial life-forms and one Earthhuman DBDG, with four radically different metabolisms and inherent species-immunity … it’s quadruply impossible! As far as I see, no indications of the other unprotected life-forms being affected.”

  Even when observing the impossible, Murchison remained clinical.

  “… But it is happening,” Conway went on. He turned up the volume of his suit external speaker. “This is Senior Physician Conway. Instructions. All transfer team-members, seal your helmets. Team leader, sound the alarm for Contamination One. Everyone else, move away from the patient They were doing so already, Conway could see, with a degree of haste that verged on panic. “Beings already wearing protective suits stand clear, unprotected oxygen-breathers go to the pressure litter and as many as po
ssible seal yourselves inside. Everyone else should use the breathing masks and oxygen supplies for the ward ventilators. We seem to be affected by some kind of airborne infection—”

  He broke off as the observation ward’s main screen flicked on to show the features of the irate Chief Psychologist. As O’Mara spoke Conway could hear in the background the repeated long and two short blasts on the emergency siren, which gave added urgency to the words.

  “Conway, why the blazes are you reporting lethal contamination down there? Dammit, there can’t be a lethal contamination of air and water unless the place is flooded and you’re all drowning, and I see no evidence of that!”

  “Wait,” said Conway. He was kneeling by the fallen transfer team-member, his hand inside the open visor, feeling for a pulse at the temporal artery. He found it, a fast, irregular beat that he did not like at all. Then he sealed the man’s visor quickly and went on speaking to the ward: “Remember to close any breathing orifices not covered by your masks, nostrils, Melfan gills, the Kelgian speaking mouth. And you, the protected Illensan doctor, will you check Thornnastor and the Melfan Edanelt, quickly please. Prilicla, how is the original patient?”

  The chlorine-breather waddled rapidly towards the fallen Thornnastor, its transparent suit rustling. “My name is Gilvesh, Conway. But all DBDGs look the same to me, so I suppose I should not feel insulted.”

  “Sorry, Gilvesh,” said Conway. The chlorine-breathing Illensans were generally held to be the most visually repulsive species in the Federation as well as the most vain regarding their own physical appearance. “A snap diagnosis, please. There isn’t time for anything else. What happened to it, and what are the immediate physiological effects?”

  “Friend Conway,” said Prilicla, still trembling violently, “the DBPK patient is feeling much better. It is radiating confusion and worry, but no fear and minimum physical discomfort. The condition of the other four concerns me deeply, but their emotional radiation is too faint to identify because of the high level of emotion pervading the ward.”

  “I understand,” said Conway, who knew that the little empath could never bring itself to criticize, however mildly, another being’s emotional shortcomings. “Attention, everyone. Apart from the four people already affected there is no immediate sign of the condition, infection, whatever it is, spreading. I would say that anyone protected by the pressure litter envelope or breathing through a mask is safe for the time being. And calm yourselves, please. We need Prilicla to help with a quick diagnosis on your colleagues, and it can’t work if the rest of you are emoting all over the place.”

  While Conway was still speaking, Prilicla detached itself from the ceiling and fluttered across on its iridescent wings to the heap of silvery fur that was the Kelgian theater nurse. It withdrew its scanner and began a physical examination concurrent with its efforts to detect, isolate and identify the creature’s emotional radiation. It was no longer trembling.

  “No response to physical stimuli,” Gilvesh reported from its examination of Thornnastor. “Temperature normal, breathing labored, cardiac action weak and irregular, eyes still react to light, but … This is strange, Conway. Obviously the lungs have been seriously affected, but the mechanism is unclear, and the curtailed supply of oxygen is affecting the heart and brain. I can find no signs of lung-tissue damage of the kind associated with the inhalation of corrosive or highly toxic material, nor anything to suggest that its immune system has been triggered off. There is no muscular tension or resistance; the voluntary muscles appear to be completely relaxed.”

  Using his scanner without unsealing the lightweight suit, Conway had examined the team-member’s upper respiratory tract, trachea, lungs and heart with exactly similar results. But before he could say anything, Prilicla joined in: “My patient displays similar symptoms, friend Conway,” it said. “Shallow and irregular respiration, cardiac condition close to fibrillation, deepening unconsciousness and all the physical and emotional signs of asphyxiation. Shall I check Edanelt?”

  “I’ll do that,” said Gilvesh quickly. “Prilicla, move clear lest I walk on you. Conway, in my opinion they require intensive-care therapy as soon as possible, and a breathing assist at once.”

  “I agree, friend Gilvesh,” the empath said as it fluttered up to the ceiling again. “The condition of all four beings is extremely grave.

  “Right,” Conway agreed briskly. “Team Leader! Move your man, the DBLF and the ELNT clear and as far from the patient as possible, but close to an oxygen supply outlet. Doctor Gilvesh will supervise fitting the proper breathing masks, but keep your team-member sealed up, with his suit air supply at fifty percent oxygen. Regarding Thornnastor, you’ll need the rest of your team to move- “Or an anti-gravity sled,” the Team Leader broke in. “There’s

  one on the next level.”

  “—it even a few yards,” Conway went on. “Considering its worsening condition, it would be better to rig an extension to an oxygen line and assist Thornnastor’s breathing where it is lying. And, Team Leader, do not leave the ward for a sled or anything else until we know exactly what it is that is loose in here. That goes for everyone … Excuse me.

  O’Mara was refusing to remain silent any longer. “So there is something loose in there, Doctor?” said the Chief Psychologist harshly. “Something much worse, seemingly, than a simple case of atmospheric contamination from an adjacent ward? Have you finally discovered the exception that proves the rule, a bug that attacks across the species’ lines?”

  “I know Earth-human pathogens cannot affect e-ts, and vice versa,” Conway said impatiently, turning to the ward screen to face O’Mara. “It is supposed to be impossible, but the impossible seems to be happening, and we need help to—”

  “Friend Conway,” Prilicla broke in, “Thornnastor’s condition is deteriorating steadily. I detect feelings of constriction, strangulation.”

  “Doctor,” the translated voice of Gilvesh joined in, “the Kelgian’s oxygen mask isn’t doing much good. The DBLF double mouth and lack of muscle control is posing problems. Positive pressure ventilation of the lungs with direct access through the trachea is indicated to avoid a complete respiratory failure.”

  “Can you perform a Kelgian tracheotomy, Doctor Gilvesh?” Conway asked, turning away from the screen. He could not think of anything to do to help Thornnastor.

  “Not without a tape,” Gilvesh replied.

  “No tape,” said O’Mara firmly, “or anything else.”

  Conway swung round to face the image of the Chief Psychologist to protest, but he already knew what O’Mara was going to say.

  “When you raised the lethal contamination alarm, Doctor,” the Chief Psychologist went on grimly, “you acted instinctively, I should think, but correctly. By so doing you have probably saved the lives of thousands of beings inside the hospital. But a Contamination One alarm means that your area is isolated until the cause of the contamination has been traced and neutralized. In this case it is much more serious. There seems to be a bug loose that could decimate the hospital’s warm-blooded oxygen-breathers. For that reason your ward has been sealed off. Power, light, communication and translation facilities are available, but you are no longer connected to the main air supply system or to the automatic food distribution network, nor will you receive medical consumables of any kind. Neither will any person, mechanism or specimen for analysis be allowed out of your area. In short, Doctor Gilvesh will not be allowed to come to me for a DBLF physiology tape, nor will any Kelgian, Melfan or Tralthan doctor be allowed to volunteer to go to the aid of the affected beings. Do you understand, Doctor?”

  Conway nodded slowly.

  O’Mara’s craggy features showed a deep and uncharacteristic concern as he stared at Conway for several seconds. It was said that O’Mara’s normally abrasive and sarcastic manner was reserved only for his friends, with whom he liked to relax and be his bad-tempered self, and that he was quiet and sympathetic only when he was professionally concerned about someone.

/>   He has an awful lot of friends, Conway thought, and right now I’m in trouble …

  “No doubt you would like to have the life-duration figures based on the residual and tanked air remaining in the ward, and the number and species of the present occupants,” the Major continued. “I’ll have them for you in a few minutes. And, Conway, try to come up with an answer …

  For several seconds Conway stared at the blank screen and told himself that there was nothing effective he could do about Thornnastor or Edanelt or the Kelgian nurse or the team-member-all of whom had suddenly switched their roles from medics to critically ill patients-without Educator tapes.

  In the normal course of events Doctor Gilvesh would have taken a DBLF tape and performed a tracheotomy on the Kelgian as a matter of course, and the Illensan senior would probably have insisted on O’Mara giving it the Tralthan tape for Thornnastor and the ELNT one for Edanelt, provided the Chief Psychologist considered Gilvesh’s mind stable enough to take three tapes for short-term use. But Gilvesh was not allowed to leave the ward even if its chlorine-breathing life depended on it, which it would very shortly.

  Conway tried not to think about the diminishing supply of air remaining in the pressure litter, where five or six e-ts were rapidly using up the tanked oxygen; or of the other beings ranged along opposing walls who were connected to breathing masks intended for patients; or of the four-hour supply carried by the transfer teammembers and himself, or of the air in the ward, which was infected and unusable, or even of the strictly limited amount of breathable chlorine carried by Gilvesh, or of the superheated atmosphere required by the TLTU. He had to think of the patients first, he told himself clinically, and try to keep them alive as long as possible. He would do this not because they were his friends and colleagues, but because they had been the first to be stricken and he had to chart the course of the infection as completely as possible so that the hospital medics of all grades and specialties would know exactly what they would have to fight.
