Randomized Controlled Trial Clinical Trial
Lignocaine as a topical analgesia for post-operative nasal pack removal: a prospective, randomized, double-blind, controlled trial.
The objective of this study was to assess the efficacy of topical lignocaine in reducing the pain of pack removal after nasal surgery. Fifty-eight patients with Merocel nasal packs in situ after nasal surgery were randomized to receive 10 ml of either 2 per cent lignocaine or 0.9 per cent saline on the packs 10 minutes prior to their removal and the pain experienced on their removal was recorded on a visual analogue scale. ⋯ There was no statistical evidence of an association between the group and the operation performed, the use of intra-operative Moffat's solution or the use of post-operative oral analgesia. We conclude that lignocaine used in this way does not reduce the pain of pack removal after nasal surgery.

Randomized Controlled Trial Clinical Trial
Comparison of nasal tampons for the treatment of epistaxis in the emergency department: a randomized controlled trial.
Nasal tampons are commonly used to stop bleeding, yet their insertion is painful. We compare the pain of insertion and removal of 2 commonly used nasal tampons. ⋯ The Rapid Rhino nasal tampon is less painful to insert and easier to remove than the Rhino Rocket, whereas both are similarly effective at stopping nosebleeds.

Randomized Controlled Trial Clinical Trial
Esophageal tamponade for bleeding varices. Controlled trial between the Sengstaken-Blakemore tube and the Linton-Nachlas tube.
To investigate the effectiveness and safety of the Sengstaken-Blakemore (SB) tube compared with the Linton-Nachlas (LN) tube, a randomized clinical trial was carried out between both types of balloon. Seventy-nine patients suffering from gastrointestinal bleeding attributed to esophagogastric varices were included in the study. ⋯ Better tolerance and greater effectiveness were obtained when the SB tube was applied without external traction. The usefulness of esophageal tamponade for bleeding varices was higher when performed within 6 hr of the onset of hemorrhage.
