exudates and Nasal-Obstruction

Objective To objectively compare the nasal decongestion potency of lidocaine/phenylephrine when delivered with a nasal nebulizer and a nasal spray before a rigid nasoendoscopic examination. Study Design Open-label randomized controlled trial. Setting Multicenter study. Methods This prospective clinical trial involved 106 participants with untreated chronic rhinitis. Fifty-three participants had 400 μL of lidocaine/phenylephrine administered into the right nostril with a nasal nebulizer, while the remaining 53 participants had 400 μL administered with a nasal spray. The control was the left nostril. Nasal resistance at 150-Pa fixed pressure was evaluated with an active anterior rhinomanometry at 5, 10, 15, and 30 minutes postintervention. Pain score was assessed subjectively by applying pressure to the inferior turbinate 30 minutes after intervention. Results There was an overall reduction in nasal resistance of the right nostril when lidocaine/phenylephrine was administered with the nasal nebulizer in comparison with the nasal spray. However, a statistically significant difference in nasal resistance was seen only at 5 minutes ( P = .047), 15 minutes ( P = .016), and 30 minutes ( P = .036). The examining endoscopist further supported the degree of nasal decongestion via subjective assessment of the nasal cavity ( P = .001). Pain scores obtained after the intervention showed a significant decrease in pain threshold when the nasal nebulizer was used instead of the nasal spray ( P = .040). Conclusions This study suggests that the delivery of lidocaine/phenylephrine to the nasal cavity by the nasal nebulizer provides better decongestive and analgesic potency as compared with the delivery by nasal sprays.

To investigate the aetiology of rhinitis occurring in pregnancy, by (1) describing the relationship between pregnancy rhinitis and serum oestrogen, progesterone, placental growth hormone and insulin-like growth factor, and (2) assessing the prevalence of pregnancy rhinitis among Malaysian women.. Prospective study involving 30 pregnant women followed at an ante-natal clinic for 14 months. Hormone levels were analysed during pregnancy and the post-partum period.. Levels of all four hormones were elevated in the third trimester, compared with first trimester and postpartum values. Rhinitis patients had higher levels of oestrogen and insulin-like growth factor 1 in the third trimester than non-rhinitis patients, although these differences were not statistically significant. The prevalence of rhinitis was 53.3 per cent, with most cases occurring in the third trimester. Patients with pregnancy rhinitis had a higher prevalence of female babies, compared with non-rhinitis patients (p = 0.003).. Pregnancy rhinitis was significantly more common in women giving birth to female babies. Women with pregnancy rhinitis had a non-significant elevation in oestrogen and insulin-like growth factor 1 levels, compared with those without rhinitis.
