颈椎手术患者一般伴有脊髓压迫、颈椎活动受限。实施全身麻醉时给气管内插管带来困难,同时经光纤喉镜直视下行气管插管也可能加重颈段脊髓的损伤。插管型喉罩(ILMA)具有更好的插管特性,在困难气道处理领域已获得认可。在置入喉罩时只需患者门齿间距大于20mm,而不需头颈明显后仰,在相对较浅麻醉状态下即可完成操作,因此对于伴有颈椎活动受限的颈椎手术患者可能具有一定程度的保护作用。有关ILMA应用于颈椎手术患者气管插管的效果还有待深入探讨。本研究拟评价ILMA用于颈椎手术患者气管插管的效果。 相似文献

Objective To observe the validity of Supreme laryngeal mask airway (SLMA) to prevent/reduce postoperative agitation after general anesthesia. Methods 180 cases of elective laparoscopic cholecystectomy were randomly assigned to SLMA group (L group, n=90) or endotracheal intubation group (T group, n=90). The incidence and severity of postoperative agitation were recorded both in the operation room and post-anesthesia care unit (PACU)(graded as 0 to 3). Results The incidence of postoperative agitation in L group was 7.78%, and 18.89% in T group (P<0.01); the severity of postoperative agitation was obviously palliated in L group than in T group (P<0.01). Conclusion Under general anesthesia, SLMA can effectively prevent/reduce the incidence of postoperative agitation in laparoscopic cholecystectomy patients. 相似文献

Adenoidectomy in paediatric outpatient surgery is assumed to require tracheal intubation (TT). The laryngeal mask airway (LMA) commonly used for general paediatric surgery has never been previously studied for adenoidectomy. We therefore prospectively compared in a randomized manner, the incidence of complications with TT and LMA in 56 children undergoing adenoidectomy. Preoperative, intraoperative and the lowest SPO 2 values after removal of either TT or LMA were recorded. The respiratory complications, cough, stridor and/or laryngospasm, were recorded intraoperatively and after removal of the airway device. The oxygen saturation levels were significantly higher in the laryngeal mask airway group both intraoperatively and after removal of the respiratory device ( P<0.05). The incidence of respiratory complications was lower in the LMA group. In conclusion we have shown that the laryngeal mask airway with a flexometallic tube is a satisfactory alternative to tracheal intubation for outpatient paediatric adenoidectomy. 相似文献

Study Objective: To determine if the TrachlightTM lightwand can facilitate FastrachTM intubation by guiding the tip of the endotracheal tube into the trachea.Design: Open-label, prospective, randomized, comparative study. Setting: General operating suites of a tertiary teaching hospital. Patients: 172 elective surgical patients requiring general anesthesia with endotracheal intubation. Interventions: With general anesthesia, the Fastrach™, which is a new intubating laryngeal mask airway, was inserted into the oropharynx. Ventilation was ensured before the insertion of an endotracheal tube via the Fastrach™. Tracheal intubation was then performed randomly (coin toss) using either the endotracheal tube alone (Fastrach™ group), or endotracheal tube with the Trachlight, a lightwand (Fastrach/Trachlight™ group). The time to place the Fastrach™ and endotracheal tube, to remove the Fastrach™, and the total time to intubate were recorded. The number of attempts, failures, trauma, sore throats, and hemodynamic changes were also recorded. Data were analyzed using unpaired t-test, ANOVA with repeated measures, or Chi-squares contingency table where appropriate. Measurements and Main Results: Although there were no differences in the times to place the Fastrach™, and endotracheal tube, the hemodynamic changes, and postoperative complications, there were significantly more attempts and failures in the Fastrach™ group compared to the Fastrach™/Trachlight™ group. There were no differences in the incidence of sore throat and trauma in between the groups. Conclusions: Although tracheal intubation is effective using a Fastrach™ alone (76% success rate), it is more effective when the Fastrach™ is used in conjunction with the Trachlight™ (95%). These results suggest that the lightwand is a useful adjunct for Fastrach™ intubation. However, the role of Fastrach™ intubation together with the Trachlight™ in the management of patients with a potential difficult airway remains to be determined. 相似文献

We conducted a prospective randomised study to compare the intubating laryngeal mask tracheal tube with a standard tube, for ease of tracheal intubation over a fibrescope. Thirty-six patients were investigated, using a sequential analysis technique. Ease of intubation was improved when the intubating laryngeal mask tracheal tube was used compared with the standard tube (p = 0.0009). Median (interquartile range [range]) intubation times (time from the tube's tip being level with the patient's teeth to successful placement) were 1.5 (1-2.3 [1-3]) s when the intubating laryngeal mask tracheal tube was used and 5 (3-7.3 [3-13]) s when the standard tube was used (p < 0.0001). 相似文献

Endotracheal intubation in infants with the Pierre Robin syndrome may sometimes be impossible to accomplish by conventional means. To aid difficult tracheal intubation many different techniques have been described. We present a case, in which we successfully intubated a small-for-date newborn boy with the Pierre Robin syndrome by using a modified laryngeal mask airway (no. 1) as a guide for the endotracheal tube. The technique is easy to perform, less traumatic and less time-consuming than multiple attempts at laryngoscopy or blind tracheal intubation. 相似文献

The haemodynamic response to the insertion of the laryngeal mask airway (LMA) was assessed and compared to that of laryngoscopy and tracheal intubation in a study of forty patients (ASA 1) randomly allocated into two groups and anaesthetised using a standard balanced anaesthetic technique. The results show that the changes in all cardiovascular parameters measured following LMA insertion were significantly less (P<0.05) when compared with those following laryngoscopy and tracheal intubation. We conclude that airway management with the LMA may be used to avoid the haemodynamic response to tracheal intubation where such a response is undersirable. 相似文献

BACKGROUND: While reports of the use of laryngeal mask airway (LMA)-Classic in great patient numbers are available, data on the use of the laryngeal tube (LT) in this age group is limited. The two devices are compared in a prospective randomized trial to evaluate success rates and quality of airway seal. METHODS: Sixty children, aged 2-8 years, scheduled for elective surgical interventions were randomized to be ventilated with LMA or LT. Standardized anesthesia was induced with fentanyl and propofol. Number of insertion attempts, time until first tidal volume and intraoperative tidal volumes, and peak pressures were recorded. Airway leak pressure was measured with cuff pressure adjusted to 60 cmH(2)O. RESULTS: Demographic data were comparable, average age in the LMA/LT group was 5.2 +/- 1.9/5.3 +/- 1.9 years. Insertion was successful in 29 of 30 patients in the LMA group (second attempt 8) and in all patients in the LT group (second attempt 3). Time until first tidal volume for LMA/LT was 23.1 +/- 7.3/19.2 +/- 8.6 s (P < 0.05). Peak airway pressures for LMA and LT were 15.3 +/- 3.4 and 17.1 +/- 4.0 cmH(2)O (P < 0.05) with tidal volumes of 10.2 +/- 2.2 and 10.2 +/- 1.9 ml.kg(-1), airway leak pressure was 19.2 +/- 8.6 cmH(2)O for LMA and 26.3 +/- 7.3 cmH(2)O for LT (P < 0.001). CONCLUSION: Insertion success rate is high with both LMA and LT in the age group studied. The airway leak pressure, serving as an estimate to judge quality of airway seal, is higher with the LT. 相似文献

The laryngeal mask airway has been used increasingly in clinics but is seldom applied in anesthesia for oral surgery, as the
mask occupies the middle of the mouth and tends to obstruct the surgical field. Here, we report the successful placement and
usage of a nasal flexible laryngeal mask airway (FLMA) in an oral surgical procedure. Fifteen patients undergoing dental procedures
under general anesthesia were studied. We clinically applied a previously reported method for inserting an FLMA with some
modifications. There was no significant bleeding from the intubated nostril in any of the patients. None of the patients complained
of sore throat, coughing, hoarseness, or any discomfort in the nose. Although we anticipate that further refinements of the
technique may be possible and that the safety of this method using a nasal FLMA needs to be assessed in a greater number of
patients, in this preliminary study we provide a proof-of-principle demonstration of the efficacy of nasal LMA ventilation
as a method of airway management for oral surgery. 相似文献
