ABSTRACT
INTRODUCTION: Anesthetists come in contact with more than two-third of hospital patients. Timely referral to anesthetists is vital in perioperative and remote site settings. Delayed referrals, improper referrals, and referrals at inappropriate levels can result in inadequate preparation, perioperative complications, and poor outcome. METHODS: The self administered paper survey to delegates attending anesthesia conferences. Questions were asked on how high-risk, emergency surgical cases remote site and critical care patients were referred to anesthetists and presence of rapid response teams. RESULTS: The response rate was 43.8%. Sixty percent (55.3-64.8, P - 0.001) reported high-risk elective cases were referred after admission. Sixty-eight percent (63.42-72.45, P - 0.001) opined preoperative resting echocardiographs were useful. Six percent (4.16-8.98, P - 0.001) reported emergency room referral before arrival of the patient. Twenty-five percent (20.92-29.42, P - 0.001) indicated high-risk obstetric cases were referred immediately after admission. Consultants practiced preoperative stabilization more commonly than residents (32% vs. 22%) (P - 0.004). For emergency surgery, resident referrals occurred after surgery time was fixed (40% vs. 28%) (P - 0.012). Residents dealt with more cases without full investigations in obstetrics (28% vs. 15) (P = 0.002). Remote site patients were commonly referred to residents after sedation attempts (32% vs. 20%) (P = 0.036). Only 34.8 said hosptals where tbey practiced had dedicated cardiac arrest team in place. CONCLUSIONS: Anesthetic departments must periodically assess whether subgroups of patients are being referred in line with current guidelines. Cancellations, critical incidents and complications arising out of referral delays, and improper referrals must be recorded as referral incidents and a separate referral incident registry must be maintained in each department. Regular referral audits must be encouraged.
ABSTRACT
AIMS AND OBJECTIVES: The aim of our study is to compare the efficacy and side-effects of Ketamine and Midazolam administered nasally for the pediatric premedication. MATERIALS AND METHODS: We studied 100 American Society of Anesthesiology I and II children aged from 1 to 10 years undergoing various surgical procedures. Totally, 50 children were evaluated for nasal ketamine (using 50 mg/ml vials) at the dose of 5 mg/kg and the other 50 received nasal midazolam 0.2 mg/kg, before induction in operation theater each patient was observed for onset of sedation, degree of sedation, emotional status being recorded with a five point sedation scale, response to venipuncture and acceptance of mask, whether readily, with persuasion or refuse. RESULTS: The two groups were homogenous. Midazolam showed a statistically significant early onset of sedation (10.76 ± 2.0352 vs. 16.42 ± 2.0696 min). There were no significant differences in venipuncture score, sedation scale at 20 min, acceptance of mask and oxygen saturation throughout the study. Significant tachycardia and 'secretions were observed in the ketamine group intra operatively. Postoperatively emergence (8% vs. 0%) and secretions (28% vs. 4%) were significant in the ketamine group. Nausea and vomiting occurred in l6% versus 10% for midazolam and ketamine group. CONCLUSIONS: Both midazolam and ketamine nasally are an effective pediatric premedication. Midazolam has an early onset of sedation and is associated with fewer side-effects.
ABSTRACT
Betel quid is used by 10-20% of world of population. Oral submucus fibrosis (OSF) is a chronic premalignant disease common in South Asian countries where betel quid is chewed. It is characterized by juxtaepithelial fibrosis of oral cavity and limited mouth opening, which can cause difficult intubation. A recent study in Taiwan has revealed long-term betel nut chewing is not predictor of difficult intubation. We describe two cases of OSF and critically analyze this study and its implications for clinical practice. OSF is now seen in Saudi Arabia and western countries with use of commercial betel quid substitutes. Although betel quid without tobacco is used in Taiwan, available evidence suggests rapid and early development of OSF where commercial chewing products like Pan Masala are used in India. Effects of betel quid may vary depending on the composition of quid and chewing habits. Studies where personal habits are involved must be analyzed carefully for external validity. Even though, Taiwan study is controlled, its validity outside Taiwan is highly questionable. Since OSF can cause unanticipated difficult intubation, thus during preanesthetic assessment, history of betel quid chewing, more importantly use of commercial chewing products is more likely to give clues to severity of OSF and possible difficult intubation. Further controlled trails in populations where commercial chewing products are used is necessary to detect association of chewing habits and difficult intubation.
