President Reagan's doctors announced today that he would probably leave the hospital for the White House tomorrow but that he probably would not have the stamina to return to work in the Oval Office for another week. A potential complication could cause the President to defer his return home until Sunday, but Dr. Dennis S. O'Leary, medical spokesman for George Washington University Hospital, said he would be ''amazed'' if it did. The potential difficulty arises from the appearance in Mr. Reagan's chest X-ray of ''a tiny little pocket'' of air, a half-inch in diameter, in the left lung, which Dr. O'Leary said suggested the possibility of an abscess, or walled off area of infection. Dr. O'Leary said, however, that the doctors continued to believe the President had no infection because his temperature and white blood cell count were both normal. Decision Based on X-rays Dr. O'Leary said the pocket was being watched to see if it became larger and began collecting fluid that would normally be secreted from the bronchial tubes and then coughed up. If the X-rays tomorrow show that the pocket is preventing Mr. Reagan's lung from draining the fluids effectively, he might stay in the hospital another day, Dr. O'Leary said.

Governor Carey announced an agreement today with four county executives on a revised program to have the state assume local Medicaid costs over the next seven years. The revised proposal was part of Mr. Carey's campaign to win support for his Medicaid plan, which has been opposed by the leader of the Senate's Republican majority, Warren M. Anderson of Binghamton, and has been called the major obstacle to approval of the state budget. The Governor announced that he had invited all the legislative leaders to his office for a meeting on Sunday. But by the end of the day, the deadlock that has left the state without a budget and unable to pay its bills the last 10 days appeared no closer to a resolution.

The conflict between ideological purists and those who bear the responsibility for moving legislation through Congress was demonstrated anew last night when three Republican Senators helped to sidetrack an austere budget proposed by a Republican President. In the Senators' view, the budget was not conservative enough. Each of them had campaigned for a balanced budget, and they said they had voted against the proposal in the Senate Budget Committee because the committee's own economic projections were that the budget would not be balanced by 1984. The vote that defeated the President's proposal, as readjusted by the committee, was 12 to 8 with nine Democrats and the three Republicans opposing the proposal.

Acting after Prime Minister Wojciech Jaruzelski threatened to resign if it did not move to prevent new strikes, the Polish Parliament approved a resolution tonight for a two-month suspension of strikes and threats to strike. The vote was overwhelmingly in favor, with only four abstentions among the 440 members. It came shortly before midnight after almost 14 hours of debate. Before the vote, leaders of the independent union Solidarity, meeting in Gdansk, issued a statement expressing ''deep anxiety'' over the Prime Minister's virtual ultimatum. The statement said that the way to avert strikes was ''by eliminating the causes through upholding the law and fulfilling the agreements.''

A mysterious computer breakdown caused postponement of the launching of the space shuttle Columbia today, and space agency officials pressed to reschedule it for Sunday morning. The earliest the orbital test mission could get under way is 6:50 A.M. Sunday. But until the computer problem in the spaceship could be corrected the officials were unable to say when the re-usable winged Columbia would be cleared for another launching attempt. Tonight engineers at the Johnson Space Center in Houston identified the source of the malfunction as a timing fault in one set of spaceship computers that disrupted communications with the backup computer.
