Guillain Barre Syndrome is one of the leading diseases from Acute Flaccid Paralysis after the decrease in poliomyelitis. In Guillain Barre Syndrome, the motoric muscles becomes weak and it could also attack the respiratory muscle which is life threatening to patients. The objective of this study is to report Guillain Barre Syndrome cases from June 1999 until June 2005 based on the clinical manifestation and laboratory in children care unit of dr. Saiful Anwar hospital. In this research there were 38 Guillain Barre Syndrome cases which were diagnosed using the Gilroy and Meyer criteria. 22 patients (57,9%) were male, 16 patients (42,1%) were female. 18 patients (43,36%) were below 5 years of age, 13 patients (34,21%) were between 5 to 10 years of age and 7 patients (18,42%) were between the age of 10 to15 years. The most common infection that precedes was upper respiratory infenction which amounts to 32 cases (84,21%). The latent phase between 8 to 14 days were 11 patients (28,94%) and 15 to 21 days were 22 patients (57,89%). The progresive phase 1 to 7 days occured in 17 patients (44,73%), 8 to 14 days also in 17 patients (44,73%).The clinical features were paresthesias followed by weakness to 23 patients (60,52%) and weakness only in 15 patients (39,47%). The pattern of weakness by tetraparese in 5 patients (13,15%) and paraparese in 33 patients (86,84%). The distribution of weakness was more towards the distal extremities then the upper extremities which amounts to 37 patients (97,36%). Laboratories examination of the cerebro spinal fluid revealed protein above 46 mg/dl in 31 patients (81,57%) and below 45 mg/dl in 7 patients (18,42%). One of the patients was on a ventilator because of respiratory muscle paralysis. Complete recovery in this research between 3 to 6 months. Guillain Barre Syndrome is clinically fully recovered although special precautions has to be taken due to the effect towards the respiratory muscle. The characteristic of the laboratory examination is an albuminocytologic dissociation
