RT Journal Article SR Electronic T1 Holding the baby: head downwards positioning for physiotherapy does not cause gastro-oesophageal reflux JF European Respiratory Journal JO Eur Respir J FD European Respiratory Society SP 954 OP 957 DO 10.1183/09031936.98.12040954 VO 12 IS 4 A1 GE Phillips A1 SE Pike A1 M Rosenthal A1 A Bush YR 1998 UL http://erj.ersjournals.com/content/12/4/954.abstract AB The head-downwards tipped position for physiotherapy has been claimed to exacerbate gastro-oesophageal reflux (GOR) in infants with cystic fibrosis (CF). This was investigated using lower oesophageal pH monitoring during physiotherapy. Twenty-one infants (age range 1-27 months) with respiratory disorders (CF=11), undergoing lower oesophageal pH monitoring were recruited. Subjects received two physiotherapy episodes in random order, A/B or B/A, 12 h apart. A began the gravity-assisted positioning head downward tip for: right lower lobe, middle lobe, left lower lobe and lingula; then supine with no tip for anterior segments of the upper lobes followed by apical segments of upper lobes in a sitting position. B was in the reverse order. Intermittent chest clapping was carried out for 4 min in each position by a physiotherapist blinded to the pH data. During episode A, the median change in pH from baseline was -0.32 (range -2.07 to +1.0) in non-CF subjects (NS) and -0.52 (range -2.7 to +0.52) in CF subjects (p<0.02). During episode B, the median change in non-CF subjects was -0.1 (NS; range - 1.7 to -0.15) and in CF subjects was -0.05 (NS; range -0.67 to +0.5). There was no order effect for positioning. In the CF subjects the sitting position was twice as likely to have the lowest pH measurement during physiotherapy than the other positions (p<0.04). In conclusion, the head-downward tipped positioning for physiotherapy treatment neither induces nor aggravates gastro-oesophageal reflux. There is no justification for routinely changing the way in which infant physiotherapy is carried out.
