King Vision video laryngoscope for severe post burn contracture neck: an encouraging experience / Videolaringoscópio King Vision para contratura grave do pescoço após queimadura: uma experiência encorajadora

Abstract Background and objectives Managing the airway of post burn contracture of the neck has always been challenging to anesthesiologists as it limits the alignment of oro-pharyngo-laryngeal axes because of functional and anatomical deformities that occur as a result of long standing contractures. Here the role of the King Vision video laryngoscope which is the latest in the series of video laryngoscope has been evaluated for such patients. Case report A 35 year old male patient with post burn contracture of neck was scheduled for release of the contracture. As the patient had had fixed flexion deformity of the neck we did not attempt the conventional laryngoscopy. Instead we opted for King Vision video laryngoscope. Conclusion We therefore conclude that King Vision videolaryngoscope can be used for difficult airway situations like post burn contracture of neck.

Resumo Justificativa e objetivos O manejo de vias aéreas em contratura de pescoço após queimadura sempre foi um desafio para os anestesiologistas, pois a contratura limita o alinhamento do eixo orofaringolaríngeo devido às deformidades funcionais e anatômicas que ocorrem como resultado de contraturas de longa duração. Relato de caso Paciente do sexo masculino, 35 anos de idade, com contratura do pescoço após queimadura foi programado para liberação da contratura. Como estava com deformidade fixa em flexão no pescoço, não tentamos a laringoscopia convencional e optamos por usar o videolaringoscópio King Vision. Conclusão O videolaringoscópio King Vision pode ser usado em situações de via aérea difícil como a contratura de pescoço após queimadura.

A comparative evaluation of Video Stylet and flexible fibre-optic bronchoscope in the performance of intubation in adult patients.

BACKGROUND AND AIMS: Video Stylet (VS) is a new intubating modality that provides real-time video of endotracheal intubation (ETI). This device does not need alignment of the oral, pharyngeal and tracheal axes to view glottis and can be used in patients with limited mouth opening. The aim of this study was to compare flexible fibre-optic (FO) bronchoscope with VS in elective surgical patients in apparently normal airway patients requiring oral ETI. METHODS: Sixty patients undergoing elective surgery under general anaesthesia of age group 20-60 years, weight 40-70 kg, American Society of Anesthesiologist 1 and 2 and modified Mallampatti I and II were included in the study. Patients in group FO (n = 30) were intubated by flexible FO bronchoscope, whereas patients in group VS (n = 30) were intubated by VS. Primary outcome measure was time taken for intubation (TTI). Secondary outcome measures were successful intubation, haemodynamic response and post-operative complications if any. RESULTS: Average TTI in cases of FO group was 38.2 s (95% confidence interval [CI] 36-41) and in VS group was 19.7 s (95% CI 19-21; P = 0.0001). Three patients required a second attempt for successful intubation in FO group compared to eight in VS group (P = 0.2), with no failures in any group. Haemodynamic response and complications rate were greater in VS group; however, the differences were not statistically significant. CONCLUSION: VS takes lesser time to intubate than flexible FO bronchoscope.

King Vision video laryngoscope versus Lightwand as an intubating device in adult patients with Mallampatti grade III and IV patients.

STUDY OBJECTIVE: Anticipated and unanticipated difficult airways are often encountered by anesthesiologists in their clinical practice. There are various devices available in such situations. We aim to compare King Vision video laryngoscope and Lightwand for their performance as an intubating device in predicted difficult intubation. DESIGN: Prospective, randomized, single blind study. SETTING: Jawaharlal Nehru Medical College. PATIENTS: Sixty ASA 1 and 2 with Mallampati grade III and IV. INTERVENTIONS: Patients were divided into 2 groups of 30 patients each. Patients of King Vision group [n=30] and Lightwand group [n=30] were intubated using respective devices. Primary outcome measure was time taken to intubate whereas secondary outcome measure ware number of attempts for intubation, no of adjustment maneuvers, changes in heart rate and mean arterial pressure and airway trauma. MEASUREMENTS AND MAIN RESULTS: Mean intubation time using King Vision video laryngoscope (19.50±6.73 seconds was lower than the intubation time using Lightwand 25.40±7.42 s, P=.00). The difference between number of attempts, success of intubation, numbers of adjustment maneuvers were comparable. There was a significant rise in heart rate within the groups from the pre-induction values. However inter group variations were similar. In addition, there was a significant rise in mean arterial pressure within the groups from the pre-induction values. Inter group variations show less increase in mean arterial pressure with Lightwand at immediate post intubation (P=.0234) and at 3 min and 5 min post intubation anesthesia.

A comparative evaluation of the Airtraq and King Vision video laryngoscope as an intubating aid in adult patients.

Airtraq has been shown to improve ease of intubation in patients with normal and difficult airway. King Vision video laryngoscope is a newly introduced intubating device with an attached monitor. We here hypothesized that the King Vision video laryngoscope with channeled blade performs better during intubation as compared to Airtraq. In this study, we performed a comparison between the King Vision video laryngoscope and the Airtraq with regard to time needed for intubation, number of attempts required to intubate, and complications. Fifty ASA grade I and II adult patients posted for a routine surgical procedure were randomly divided into two groups of 25 patients each. All patients were anesthetized using similar techniques. The time required to intubate patients was significantly shorter when the King Vision video laryngoscope with channeled blade was used as compared to the Airtraq (p < 0.05). The number of attempts to successfully intubate patients was also significantly lower (p < 0.05) for the King Vision video laryngoscope than for the Airtraq. The use of the Kings Vision video laryngoscope with channeled blade should be encouraged in difficult intubation situations in adult patients with a mouth opening of more than 18 mm.

Management of accidental extubation during oral surgery by nasotracheal intubation using the King vision video laryngoscope and a gum elastic bougie - a case report.

Accidental extubation during intra operative period especially during oral surgery is challenging for any anaesthesiologist. Securing the definitive airway during this period is not only crucial and life saving but also challenging to the anaesthesia provider. Here we report a case which got extubated during hemimandibulectomy and was successfully reintubated using King Vision video laryngoscope. This videolaryngoscope proved to be a good rescue device in managing an accidental extubation during oral surgery and could represent a useful tool for the management of such unfamiliar situations.

Comparison of the Airtraq and McCoy laryngoscopes using a rigid neck collar in patients with simulated difficult laryngoscopy.

STUDY OBJECTIVE: To determine the efficacy of the Airtraq versus the McCoy laryngoscope as intubation devices with the neck stabilized by a rigid cervical collar. DESIGN: Prospective, randomized, double-blinded study. SETTING: Jawaharlal Nehru Medical College. PATIENTS: 60 ASA physical status 1, 2, and 3 patients, aged 18-70 years, scheduled for various surgical procedures requiring tracheal intubation for surgical anesthesia. INTERVENTIONS: Patients were randomly allocated to undergo intubation with the McCoy (n = 30) or Airtraq (n = 30) laryngoscope. MEASUREMENTS AND MAIN RESULTS: Differences in intubation times between the Airtraq and the McCoy laryngoscope, modified Cormack-Lehane score, percentage of glottic opening (POGO) score, and airway trauma were compared. Overall intubation success rates were 100% with both devices and a similar number of intubation attempts were required. However, the mean (SD) time required for successful intubation was shorter with the Airtraq (28.73 ± 6.39 sec) than the McCoy laryngoscope (39.11 ± 14.01 sec; P < 0.0001). The frequencies of intubation complications were similar. Esophageal intubation occurred in 4 cases but only with the McCoy laryngoscope. CONCLUSION: Intubation time was shorter with the Airtraq than the McCoy laryngoscope, even though the overall success rates between the two devices were similar.

Efficacy of clonidine as an adjuvant to ropivacaine in supraclavicular brachial plexus block: A prospective study.

BACKGROUND AND AIMS: Bupivacaine has been the most frequently used local anaesthetic in brachial plexus block, but ropivacaine has also been successfully tried in the recent past. It is less cardiotoxic, less arrhythmogenic, less toxic to the central nervous system than bupivacaine, and it has intrinsic vasoconstrictor property. The effects of clonidine have been studied in peripheral nerve blockade. The purpose of this study was to evaluate the effects of clonidine on nerve blockade during brachial plexus block with ropivacaine using peripheral nerve stimulator. METHODS: Sixty patients were randomly divided into two groups, Group A and B. Group A received 30 ml of 0.5% of ropivacaine with 0.5 ml normal saline while Group B received same amount of ropivacaine with 0.5 ml (equivalent to 75 µg) of clonidine for supraclavicular brachial plexus block. The groups were compared regarding quality of sensory and motor blockade, duration of post-operative analgesia and intra and post-operative complications. RESULTS: There was a significant increase in duration of motor and sensory block and analgesia in Group B as compared to Group A patients (P < 0.0001). There was no significant difference in onset time in either group (P = 0.304). No significant side effects were noted. CONCLUSION: The addition of 75 µg of clonidine to ropivacaine for brachial plexus block prolongs motor and sensory block and analgesia without significant side effects.

Airtraq(®) optical laryngoscope for tracheal intubation in patients with severe ankylosing spondylitis: A report of two cases.

Airway management in patients of ankylosing spondylitis remains a challenge for anaesthesiologists. Many new airway devices have been used for securing airway in these patients. The Airtraq(®) optical laryngoscope is one of the new rigid laryngoscopes with a proximal view finder that reflects an image transferred from the distal tip of the blade through a series of lenses, prisms and mirrors. We report two cases of ankylosing spondylitis who were scheduled for total hip replacement and subtotal thyroidectomy and were successfully intubated using the Airtraq(®) laryngoscope.
