GlideScope-assisted nasotracheal intubation (NTI) has been proposed as an alternative to difficult orotracheal intubation for critical patients or those under cervical immobilization. We evaluated the difficulty of performing NTI using GlideScope under cervical orthosis. A total of 170 patients scheduled for elective cervical spinal surgery that required NTI were randomized to receive cervical immobilization using a cervical collar (collar group) or no cervical immobilization at all (control group) before anesthetic induction (group assignment at 1:1 ratio). All NTI during anesthetic induction were performed using the GlideScope. The primary outcome was time to intubation. The secondary outcomes were ease of intubation, including the necessity of auxiliary manipulations to assist intubation, and the nasotracheal intubation difficulty scale (nasoIDS). An exploratory analysis identified morphometric parameters as predictors of time to intubation, the necessity of auxiliary manipulations, and a nasoIDS score ≥ 4. For time to intubation, the mean difference (collar group—control) was − 4.19 s, with a 95% confidence interval (CI) of − 13.9 to 5.52 that lay within our defined equivalence margin of 16 s. Multivariate regressions precluded the association of cervical immobilization with a necessity for auxiliary manipulations (adjusted odds ratio [aOR] 0.53, 95% CI [0.26–1.09], P = 0.083) and a nasoIDS ≥ 4 (aOR 0.94 [0.84–1.05], P = 0.280). Among all morphometric parameters, the upper lip bite test class was predictive of a longer time to intubation (all analyses relative to class 1, 14 s longer for class 2, P = 0.032; 24 s longer for class 3, P = 0.070), increased necessity for auxiliary manipulation (aOR 2.29 [1.06–4.94], P = 0.036 for class 2; aOR 6.12 [1.04–39.94], P = 0.045 for class 3), and nasoIDS ≥ 4 (aOR 1.46 [1.14–1.89], P = 0.003 for class 3).The present study demonstrated that GlideScope achieved NTI in patients with or without cervical immobilization equivalently with respect to intubation time and ease.
Pancreatic squamous cell cancer (PSCC) is a rare and aggressive form of pancreatic cancer that has a poor prognosis. The 5-year survival rate for PSCC is estimated to be approximately 10%, and the median overall survival time is 6 to 12 months. Treatment options for PSCC include surgery, chemotherapy, and radiation therapy, but the outcomes are usually not very favorable. The outcomes depend on the stage of the cancer and the patient’s overall health and response to treatment. The optimal management remains early diagnosis and surgical resection. We present a rare case of PSCC with spleen invasion, which arises from a large cyst with eggshell calcification, the patient was treated by surgical resection of the tumor and adjuvant chemotherapy. This case report emphasizes the necessity of regular follow for pancreatic cyst.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
