Pre-operative breathing training based on video learning reduces emergence delirium in preschool children: A randomized clinical trial.

STUDY OBJECTIVE: Emergence delirium is a common complication in preschool children after general anesthesia and may result in undesirable complications. This study aimed to determine whether breathing training after watching an informative video during the pre-operative visit could reduce the incidence of emergence delirium in preschool children after otorhinolaryngologic surgery under general anesthesia. DESIGN: A single-center, double-blinded, randomized controlled trial. SETTING: Perioperative care. PATIENTS: A total of 170 children undergoing otorhinolaryngologic surgery, aged 3-7 years, ASA physical status I or II were involved. INTERVENTIONS: Patients were randomized to receive breathing training during the pre-operative visit (Training group) or to receive pre-operative visit only (Control group) the day before surgery. MEASUREMENTS: Emergence delirium was measured by the Pediatric Anesthesia Emergence Delirium score during the anesthesia recovery time. Data regarding extubation time and post-anesthesia care unit stay time were collected. MAIN RESULTS: Children who received breathing training during the pre-operative visit had a significantly lower incidence of emergence delirium than those who only underwent the pre-operative visit (10.4% vs. 35.1%, P < 0.001). The awakening time score and the maximum score in the post-anesthesia care unit were significantly lower in the training group compared with the control group [4.4 ± 3.4 vs. 6.9 ± 4.2, P < 0.001 and 5.0 (5.0) vs 7.0 (7.0), P = 0.001, respectively]. We found no differences in the extubation time and post-anesthesia care unit stay time between groups. CONCLUSIONS: We concluded that breathing training based on video learning during the pre-operative visit in preschool children undergoing otorhinolaryngologic surgery could significantly decrease the incidence of emergence delirium.

The end-of-treatment telephone response and prognosis of post-radiotherapy nasopharyngeal carcinoma patients in southern China.

Nasopharyngeal Carcinoma (NPC) patients' end-of-treatment survival status has drawn more attention in recent years. Telephone follow-up, as a most operative approach among all the clinical follow-ups, is an effective means to extend medical service to patients' home and is thus widely used in clinical practice. This study aimed to analyze the post-radiotherapy NPC patients' phone response rate and its factors, and to discuss the independent prognostic factors of NPC patients' radiotherapy. We prospectively designed a nurses-led telephone follow-up to include 2520 NPC patients who received simple radical radiotherapy between Jan. 2007 and Jun. 2012 at Sun Yat-sen University Cancer Center. The patients' response rate and its factors were calculated. Survival analysis was used to estimate the patients' survival and the influencing factors. The overall response rate was 90.5%; Patients with reserved contact type of mobile + landlinephone or landline phone had higher follow-up response rate than patients with mobile contact only; patients with 2 or more reserved contacts, and family cancer history had higher response rate than patients with only 1 number and those without family history. Patients' cumulative survival rate of 1, 3 and 5 years were 98.9%, 75.3%, 50.3%, respectively. T-staging, N-staging, higher clinical staging, with basicranial invasion were the influencing factors of the patients' poor prognosis. The telephone follow-up response was affected by reserved contact type, number of contacts and family medical history; T-staging, N-staging, higher clinical staging, with basicranial invasion were the influencing factors of the patients' poor prognosis. This study provides a scientific basis for increasing the NPC patients' end-of-treatment response and promoting the individualized clinical treatment.
