Background: Reduced manual dexterity and hand comfort affect all people exposed to extreme cold. Ointment nitroglycerine 0.2% (NTG) and ointment salbutamol 0.5% (Sal) applied topically to the extremities could result in increased local blood flow and temperature, improving hand comfort and dexterity in extreme cold. Aim and Objectives: This study was designed to elucidate if the application of NTG or Sal would improve manual dexterity and hand comfort in extreme cold conditions. Materials and Methods: A double-blind, randomized controlled trial was conducted at 3500 m altitude in 105 individuals divided into three equal-sized groups. Group A received NTG, Group B placebo (white soft paraffin), and Group C Sal, for application to the extremities twice daily, for 2 weeks. Hand skin temperatures (Tsk), Pegboard scores, and a Graphic Rating Scale (GRS) for pain were compared before and after the intervention. Adverse effects and user acceptability criteria were recorded. Results: Participants of all three groups showed significant improvement in Tsk, Pegboard scores, and GRS scores postintervention, however none of the parameters were different between groups. The acceptability questionnaire scores were best in the placebo group. Conclusion: Neither NTG nor Sal was superior to placebo for improvement in hand comfort or dexterity, in extreme cold at high altitude.
