Medical education: Effectiveness of two simulation teaching methods in developing intubation skills of year level six medical students (clinical clerks)

@#<p style="text-align: justify;"><strong>OBJECTIVE:</strong> To describe outcomes of two simulation teaching methods in developing intubation skills of year level six medical students (clinical clerks).<br /><strong>METHODS:</strong> Students were shown a 6-minute video on intubation. Students were exposed to video-assisted learning, video-assisted learning with instructor-guided simulation, and video-assisted learning with experiential learning. Each student was assessed by a non-graded 11 point objective structured clinical examination.<br /><strong>RESULTS AND DISCUSSION:</strong> The three learning strategies: 1. Video-assisted learning, 2. Video-assisted learning with instructor-guided simulation, 3. Video-assisted learning with experiential learning (self-discovery learning) simulation showed OSCE mean scores (standard deviations) of 5.76 (2.16), 7.21 (2.35) and 7.60 (1.72), respectively. Failure of intubation was 21% (8/38), 2% (1/40) and 0% (0/36), respectively. There is an absolute risk reduction of 27-30% in failure of intubation when either VGL or VEL is used. Students recognized the contribution of the simulation-based activities to the development of their intubation skills. They appreciated the opportunity to actually perform intubation in a rehearsal setting before doing the procedure on real patients.<br /><strong>CONCLUSION:</strong> Medical simulation enhanced student skills development. Experiential learning or self-discovery learning method may be as effective as instructor guided simulation.</p>

The usefulness of performing extensive debridement to prevent infections in open flexor tendon injuries of the hand

BACKGROUND: Infection after flexor tendon repair in the hand is uncommon but may cause debilitating problems if not prevented. In centers where delayed presentation after injury happens often, early bacterial colonization is assumed and an initial debridement is indicated ensuring a clean environment for subsequent repair. Preference for the type of initial debridement differ from surgeon to surgeon. OBJECTIVE: This paper aims to compare limited and extensive initial debridement in preventing post-operative infection in patients treated more than 24 hours after open tendon injury. METHODS: A retrospective review of records for demographics, the type of debridement and occurrence of infection was performed. Statistical comparison of proportions of post-operative infection was done. RESULTS: Of thirty-one records included, twenty-four patients underwent extensive debridement while 7 had limited. Two patients from each group developed infections resulting to 8.3 % infection in the extensive group and 28.6 % in the limited group. The difference is not statistically significant. CONCLUSION: The trend for a higher infection rate in the limited group supports the need for aggressive debridement in managing delayed presenting patients with open tendon injuries. While the non-significant difference potentially supports the less cumbersome option, a better powered study is recommended to confirm.
