A Cochrane review [Abstract] 1 included 2 studies with a total of 268 subjects. Pooling of data was not possible. In one study there was no evidence of improved effectiveness with the addition of a non-steroidal anti-inflammatory drug (tenoxicam) to routine recompression therapy (at 6 weeks RR for recovery with tenoxicam 1.04, 95% CI 0.90 to 1.20) but there was a reduction in the number of compressions required when tenoxicam was added from 3 to 2 (P = 0.01, 95% CI 0 to 1). The RR for requiring more than two treatments with tenoxicam was 0.64 (95% CI 0.46 to 0.86; 1 study, n = 180). In the other study, the odds of multiple recompressions was lower with a helium and oxygen (heliox) table compared to an oxygen treatment table (RR 0.56, 95% CI 0.31 to 1.00, P = 0.05).
Comment: The quality of evidence is downgraded by imprecise results (few patients).
