Abstract
Simple flow diagrams, with explanatory notes, have been devised to assist in the immediate and subsequent management of patients presenting to casualty departments with spontaneous pneumothorax. They cover decision making about which patients require admission; whether a drainage procedure is necessary; if so, the appropriate method, including technical details; inpatient treatment; referral of inpatients to a respiratory specialist; and follow up arrangements. The guidelines, designed for incorporation into casualty and ward handbooks, have already proved valuable in several district general hospitals, and can be used as a basis for audit.
