Effect of virtual reality on preoperative anxiety in patients undergoing septorhinoplasty

Abstract Background The aim of this study was to evaluate the effect of a virtual reality video on preoperative anxiety, hemodynamic parameters, and patient satisfaction in patients undergoing septorhinoplasty. Methods This was a prospective, observational cohort trial. Forty patients between the ages of 18-65 who were scheduled for elective septorhinoplasty, with an American Society of Anesthesiologists (ASA) physical status I-II were included in the study. Patients experienced a 15-minute virtual reality (VR) video via a phone using a VR device. A three-dimensional, 360° video depicted the beauty of nature and was accompanied by meditation music. Patients' oxygen saturation values, heart rate, and blood pressure were monitored and recorded. Using the State-Trait Anxiety Inventory scale, anxiety scores and hemodynamic parameters were compared before and after VR application. Results Median anxiety scores decreased significantly from 40.5 to 34 (p< 0.001). VR also had positive effects on hemodynamic parameters. Conclusions VR reduces preoperative anxiety and has positive effects on hemodynamic parameters in patients undergoing septorhinoplasty. We anticipate that VR will be increasingly used as a non-pharmacological preoperative approach in the future.

Rol de la cirugía endoscópica en el tratamiento de quistes odontogénicos del hueso maxilar: revisión de la literatura / Role of endoscopic surgery in the treatment of maxillary odontogenic cysts

Los quistes odontogénicos son lesiones óseas, de carácter benigno, la mayoría asintomáticas, que habitualmente corresponden a un hallazgo radiológico. El tratamiento es quirúrgico y está condicionado por factores como localización, tamaño y la afectación de estructuras vecinas. El objetivo es elegir la modalidad de tratamiento que conlleve el menor riesgo de recurrencia, la mínima morbilidad, y al mismo tiempo la erradicación de la lesión. Siguiendo esta premisa han sido abordados, tradicionalmente, con técnicas abiertas con buenos resultados, pero con el advenimiento y desarrollo de la cirugía endoscópica, se empezó a usar esta técnica en forma exclusiva o en forma mixta para la resección de los quistes odontogénicos, logrando similares tasas de éxito, pero con menores complicaciones y morbilidad posoperatoria. Además, presenta una ventaja respecto del seguimiento para las recurrencias, ya que se pueden controlar endoscópicamente en la consulta ambulatoria. El objetivo de esta revisión es describir el desarrollo del rol de las cirugías endoscópicas para el tratamiento de lesiones odontogénicas maxilares.

Odontogenic cysts are benign bone lesions, most of them asymptomatic, which usually constitute a radiological finding. The treatment is surgical and is conditioned by factors such as location, size and involvement of nearby structures. The objective is to choose the treatment mode that presents the lowest risk of recurrence, the minimum morbidity, and at the same time, the eradication of the lesion. Following this premise, the treatment of these lesions has traditionally been approached with open techniques with good results but, with the advent and development of endoscopic surgery, this technique began to be used exclusively or in a mixed form for the resection of odontogenic cysts, achieving similar rates of surgical success, but with fewer complications and postoperative morbidity. It also has an advantage regarding follow-up for recurrences, since patients can be controlled endoscopically in the outpatient clinic. The objective of this review is to describe the development and role of endoscopic surgery for the treatment of maxillary odontogenic lesions.

Descripción del manejo cosmético de la pirámide nasal complementario a cirugía ortognática. Revisión narrativa / Description of the cosmetic management of the nasal pyramid complementary to orthognathic surgery. Narrative review

RESUMEN: Objetivo: Describir los cambios de la pirámide nasal al realizar una osteotomía Le Fort I y el manejo cosmético complementario a la cirugía ortognática. Material y método: Se realizó una búsqueda electrónica en las bases de datos PubMed, EBSCO, Scopus, The Cochrane Library, y en el metabuscador Epistemonikos a través de las palabras clave "Le Fort 1", "Orthognathic Surgery", "Maxillary Surgery", "Nasolabial Changes", "Nasal Change", "Nasolabial Esthetics", "Soft Tissue", "Nasal Profile", "Nose" y "Cosmetic", relacionadas entre sí con los términos booleanos AND y OR. Resultados: se seleccionaron 25 artículos: 15 estudios observacionales, 5 revisiones narrativas, 3 ensayos clínicos y 2 notas técnicas. Conclusión: se establece cierto patrón que permitiría predecir cambios que sufrirá la nariz: aumento en la proyección nasal, disminución del largo columelar y ensanchamiento de la base alar son uno de ellos. En otros aspectos como el ángulo nasolabial o la posición final de la punta nasal no se ha logrado definir un patrón común. Para evitarlos se han descrito muchas técnicas. Sin embargo, falta mayor evidencia.

ABSTRACT: Objective: To describe the changes of the nasal pyramid when performing a Le Fort I osteotomy and its cosmetic management complementary to the orthognathic surgery. Materials and Methods: An electronic search was made in PubMed, EBSCO, Scopus, The Cochrane Library and Epistemonikos using the keywords "Le Fort 1", "orthognathic surgery", "maxillary surgery", "nasolabial changes", "nasal change", "nasolabial esthetics", "soft tissue", "nasal profile", "nose" and "cosmetic" related to each other with the Boolean terms AND and OR. Results: 25 articles were selected; 15 observational studies, 5 narrative reviews, 3 clinical trials and 2 technical notes. Conclusion: Nasal changes tend to follow a certain pattern that allows to predict them when facing surgery: increase of nose projection, decrease in columellar length and widening of the alar base, among others. As for other aspects such as the nasolabial angle or the final position of the nasal tip, it has not been possible to define a common pattern. To avoid them, several techniques have been described. However, more evidence is needed.

Algorithm for the treatment of external nasal valve insufficiency / Algoritmo para o tratamento da insuficiência de válvula nasal externa

Abstract Introduction: Nasal obstruction is one of the most prevalent complaints in the population. The main causes of nasal obstruction are inflammatory, infectious or anatomical alterations. Anatomical alterations include nasal septum deviation, turbinate hypertrophy, and nasal valve insufficiency (external and/or internal). The diagnosis of nasal valve insufficiency remains a clinical one and is based on inspection and palpation of the nose, evaluating both its static and dynamic functions. The literature presents several options for the correction of external nasal valve insufficiency. These are chosen according to the choice and experience of each surgeon. Objective: To create a practical algorithm for the treatment of external nasal valve insufficiency that can guide nasal surgeons in their choice of treatment for the different anatomical alterations found in patients with these disorders. Methods: We used the treatment options found in the literature and correlated them with our surgical options for each type of anatomical alteration found. Therefore, we used basically three parameters related to physical examination findings (degree of insufficiency and characteristics of the lower lateral cartilage) and the patient's complaint (present or absent aesthetic complaint regarding the nasal tip). Result: A practical algorithm was developed for the treatment of external nasal valve insufficiency according to the degree of insufficiency (mild-to-moderate or severe), aesthetic complaint of the nasal tip (present or absent) and characteristics of the lower lateral cartilage (size and orientation). Conclusion: Through this simple algorithm, one can use each type of graft and/or maneuver according to the patients' complaints and the anatomical alterations found.

Resumo Introdução: A obstrução nasal é uma das queixas mais prevalentes na população. As principais causas de obstrução nasal são inflamatórias, infecciosas ou alterações anatômicas. As alterações anatômicas incluem: desvio do septo nasal, hipertrofia de conchas nasais e insuficiência da válvula nasal (externa e/ou interna). O diagnóstico da insuficiência de válvula nasal permanece clínico e baseado na inspeção e palpação do nariz, avaliado em funções estática e dinâmica. Temos na literatura diversas opções de correção da insuficiência de válvula nasal externa. Essas são escolhidas de acordo com a opção e experiência de cada cirurgião. Objetivo: Criar um prático algoritmo para o tratamento da insuficiência de válvula nasal externa, que oriente os cirurgiões de nariz na escolha do tratamento para as diferentes alterações anatômicas encontradas nos pacientes portadores dessas alterações. Método: Utilizamos as opções de tratamento encontradas na literatura e relacionamos com as nossas opções cirúrgicas para cada tipo de alteração anatômica encontrada. Dessa forma, utilizamos basicamente três parâmetros relacionados aos achados de exame físico (grau de insuficiência e características da cartilagem lateral inferior) e à queixa do paciente (queixa estética da ponta nasal presente ou ausente). Resultado: Um algoritmo prático para o tratamento da insuficiência de válvula nasal externa, de acordo com o grau da insuficiência (leve-moderada ou severa), a queixa estética da ponta nasal (presente ou ausente) e as características da cartilagem lateral inferior (tamanho e orientação). Conclusão: Através desse simples algoritmo, podemos utilizar cada tipo de enxerto e/ou manobra de acordo com as queixas dos pacientes e as alterações anatômicas encontradas.

Estesioneuroblastoma: reporte de caso y revisión bibliográfica / Esthesioneuroblastoma: case report and review

Resumen El estesioneuroblastoma (ENB), también conocido como neuroblastoma olfatorio, es una neoplasia maligna rara de la bóveda nasal que se cree que surge de las células receptoras neurosensoriales en el epitelio olfatorio. El ENB representa el 3% de todos los tumores nasales. Los tratamientos para ENB incluyen cirugía, radioterapia y/o quimioterapia, aunque a veces, es difícil lograr un tratamiento radical utilizando estas estrategias, ya que la mayoría de los pacientes se diagnostican en una etapa avanzada. Presentamos el caso de un varón de 46 años a quien se le diagnosticó ENB en el año 2016. Fue tratado inicialmente con resección endoscópica nasal, seguido de una craneotomía bifrontal. Posteriormente, recibió radioterapia adyuvante. Actualmente, su seguimiento a 3 años no muestra evidencia de metástasis locales, regionales o distantes, ni recurrencia.

Abstract Esthesioneuroblastoma (ENB), also known as olfactory neuroblastoma, is a rare malignant neoplasm of the nasal vault that is believed to arise from neurosensory receptor cells in the olfactory epithelium. ENB accounts for 3% of all nasal tumors. The treatments for ENB include surgery, radiotherapy and/or chemotherapy, though sometimes, it is difficult to achieve radical treatment using these strategies as most patients are diagnosed at a late stage. We present a case of a 46-year old male who had been diagnosed with ENB in 2016. He was initially treated with nasal endoscopic resection, followed by a bifrontal craniotomy. Afterwards, he received adjuvant radiotherapy. Currently, his 3-year follow up show no evidence of local, regional o distant metastasis, nor recurrence.

Trend analysis of nasal bone fracture

BACKGROUND: Nasal bone fractures occur frequently because the nasal bone is located at the forefront of the face. The goal of this study was to examine the cause, change in severity, change in incidence, and demographics of nasal bone fracture according to today's lifestyle. METHODS: A total of 2,092 patients diagnosed as having nasal bone fractures at our department between 2002 and 2017 were included in this study. We retrospectively examined patients' medical records to extract information regarding age, sex, cause of injury, combined facial bone fractures, and related injuries such as skull base fracture, spinal cord injury, brain hemorrhage, and other bone fractures. Fracture severity was classified by nasal bone fracture type. RESULTS: No statistically significant difference was found in annual number of patients treated for nasal bone fracture. The proportion of patients who underwent closed reduction was significantly decreased over time for those with nasal bone fractures caused by traffic accidents. However, it was not significantly changed for those with nasal bone fractures due to other causes. The number of patients with combined facial bone fractures increased over time. Incidences of severe nasal bone fracture also increased over time. CONCLUSION: The study suggested that there is a decrease in the frequency and increase in the severity of nasal bone fracture due to traffic accident. Many protective devices prevent nasal bone fractures caused by a small amount of external force; however, these devices are not effective against higher amounts of external force. This study highlights the importance of preoperative thorough evaluation to manage patients with nasal bone fractures due to traffic accident.

Surgical treatment of choanal atresia with transnasal endoscopic approach with stentless single side-hinged flap technique: 5 year retrospective analysis / Tratamento cirúrgico de atresia de coana com abordagem endoscópica transnasalcom técnica de retalho único e articulação lateral sem colocação de stent: análise retrospectiva de 5 anos

Abstract Introduction: Choanal atresia is a rare congenital malformation of the nasal cavity characterized by the complete obliteration of the posterior choanae. In 67% of cases choanal atresia is unilateral, affecting mainly (71%) the right nasal cavity. In contrast to the unilateral form, bilateral choanal atresia is a life-threatening condition often associated with respiratory distress with feeding and intermittent cyanosis exacerbated by crying. Surgical treatment remains the only therapeutic option. Objective: To report our experience in the use of a transnasal endoscopic approach with stentless single side-hinged flap technique for the surgical management of choanal atresia. Methods: A 5 year retrospective analysis of surgical outcomes of 18 patients treated for choanal atresia with a transnasal technique employing a single side-hinged flap without stent placement. All subjects were assessed preoperatively with a nasal endoscopy and a Maxillofacial computed tomography scan. Results: Ten males and eight females with a mean age at the time of surgery of 20.05 ± 11.32 years, underwent surgery for choanal atresia. Fifteen subjects (83.33%) had a bony while 3 (26.77%) a mixed bony-membranous atretic plate. Two and sixteen cases suffered from bilateral and unilateral choanal atresia respectively. No intra- and/or early postoperative complications were observed. Between 2 and 3 months after surgery two cases (11.11%) of partial restenosis were found. Only one of these presented a relapse of the nasal obstruction and was subsequently successfully repaired with a second endoscopic procedure. Conclusion: The surgical technique described follows the basic requirements of corrective surgery and allows good visualization, evaluation and treatment of the atretic plate and the posterior third of the septum, in order to create the new choanal opening. We believe that the use of a stent is not necessary, as recommended in case of other surgical techniques involving the use of more mucosal flaps.

Resumo Introdução: A atresia de coanas é uma malformação congênita rara da cavidade nasal caracterizada pela obliteração completa da coana posterior. Em 67% dos casos a atresia coanal é unilateral, acomete principalmente (71%) a cavidade nasal direita. Diferentemente da forma unilateral, a atresia coanal bilateral é uma condição com risco de vida, frequentemente associada a insuficiência respiratória à alimentação e cianose intermitente exacerbada pelo choro. O tratamento cirúrgico ainda é a única opção terapêutica. Objetivo: Relatar a nossa experiência no uso de uma abordagem endoscópica transnasal com a técnica de retalho articulado de um lado só sem colocação de stent para o tratamento cirúrgico da atresia coanal. Método: Análise retrospectiva de 5 anos dos desfechos cirúrgicos de 18 pacientes tratados para atresia coanal com uma técnica transnasal com um único retalho de articulação lateral, sem colocação de stent. Todos os indivíduos foram avaliados no pré-operatório com endoscopia nasal e um exame de tomografia computadorizada maxilofacial. Resultados: Dez homens e oito mulheres com idade média de 20,05 ± 11,32 anos à cirurgia foram submetidos a cirurgia para atresia de coanas. Quinze (83,33%) apresentavam placa atrésica óssea e três (26,77%) placa atrésica ósseo-membranosa mista. Dois e 16 casos tinham atresia coanal bilateral e unilateral, respectivamente. Não foram observadas complicações intra e/ou pós-operatórias precoces. Entre 2 e 3 meses após a cirurgia dois casos (11,11%) de restenose parcial foram identificados. Apenas um deles apresentou uma recidiva da obstrução nasal e, portanto, foi reparado com sucesso com um segundo procedimento endoscópico. Conclusão: A técnica cirúrgica descrita segue os requisitos básicos de cirurgia corretiva e possibilita boa visualização, avaliação e tratamento da placa atrésica e do terço posterior do septo, a fim de criar a nova abertura coanal. Pensamos que o uso de um stent não é necessário, tal como recomendado no caso de outras técnicas cirúrgicas que envolvem o uso de mais retalhos de mucosas.

Study the Effect of Dexmedetomidine on Emergence Agitation after Nasal Surgeries

Background: Emergence agitation is a short lived phenomenon occurring commonly after nasal surgery. In this study we used dexmedetomidine infusion in that intraoperative period to decrease the incidence of emergence agitation in adult male and female patients posted for nasal surgery. Aim: Study the effect of dexmedetomidine on emergence agitation after nasal surgeries. Materials and methods: 110 adult patients (ASA I-II, 22-65 years posted for nasal surgery were randomly divided into two groups. Group D received infusion of dexmedetomidine 0.4mcg/kf/hr during the intraoperative period, and Group C received normal saline infusion as placebo. All patients were induced with fentanyl (1 mcg/kg) and propofol (1.5 mcg/kg) and maintained with isoflurane. Incidence of agitation, hemodynamics, pain scores, time to verbal commands and extubation were evaluated. Results: Incidence of emergence agitation was lower in Group D (26%) than Group C (50%). Group I showed more stable hemodynamics than Group II. Time to verbal response and extubation was more for Group D than Group C (p < 0.05) though it was not clinically significant. Conclusion: The use of dexmedetomidine as intraoperative infusion resulted in smooth emergence with more stable hemodynamics.

Effect of Nasal Surgery in Patients with Remained Snoring and Sleep Apnea after Obstructive Sleep Apnea Surgery / 대한이비인후과학회지

BACKGROUND AND OBJECTIVES: Obstructive sleep apnea syndrome is one type of sleep disorder breathing. During sleep, in respiration, nasal obstruction causes negative pressure, which in turn causes the pharyngeal airway to collapse during inspiration. We investigated how nasal surgery affects patients who have undergone OSA surgery but still suffer from the remaining symptoms of snoring and sleep disorder breathing. SUBJECTS AND METHOD: We reviewed 24 patients, who had undergone obstructive sleep apnea (OSA) surgery only to show no enhancement in snoring and qualities of sleep; they showed nasal septal deviation or inferior turbinate hypertrophy. Septal surgery or inferior turbinoplasty was performed by the same otolaryngologist. Over the period between preoperation and 1, 3, 6, 12 months after operation, we evaluated Apnea-Hypopnea Index (AHI) and oxygen saturation by polysomnography, degree of snoring by Visual Analogue Sacle (VAS) score, satisfaction for quality of sleep by Epworth Sleepiness Scale (ESS), minimal cross section area and volume of nasal cavity by acoustic rhinometry, respectively. RESULTS: After nasal surgery, the volume of nasal cavity and MCA increased. There were significant improvements of AHI, oxygen saturation, VAS and ESS score. CONCLUSION: As for OSA surgery, the evaluation of nasal cavity is an indispensible factor for improving the quality of sleep and snoring. When treating OSA patients who have nasal obstruction, nasal surgery including septoplasty and inferior turbinoplasty should be considered.

Effects of Frozen Gauze with Normal Saline on Thirst and Oral Health of the Patients with Nasal Surgery / 한국간호교육학회지

PURPOSE: The purpose of this study was to examine the effects of frozen gauze with normal saline on thirst and the oral health of patients with nasal surgery. METHODS: A quasi-experimental, nonequivalent control group pretest-post test design was used. Participants (n=52) received either gauze frozen with normal saline (n=26), or wet gauze (n=26). The subjective thirst level and oral health of the participants were assessed before the intervention, 30 minutes after the first intervention, 30 minutes after the second intervention, and 30 minutes after the third intervention. RESULTS: After oral hygiene was provided twice, the thirst level was improved in patients receiving the gauze frozen with normal saline. After oral hygiene was provided a third time, the thirst level was improved in patients receiving the gauze frozen with normal saline. CONCLUSION: Gauze frozen with normal saline can be effective for oral hygiene in reducing the thirst level and improving the oral health in nasal surgery patients.

Prospective Study on the Characteristics and Postoperative Improvement of Rhinogenic Headache

BACKGROUND AND OBJECTIVES: Headache secondary to sinonasal disease can improve after surgery, but few prospective studies have investigated this outcome. We aimed to evaluate the characteristics of headaches, such as clinical features, underlying disease, and postoperative improvement in patients who underwent nasal surgery, and to identify the characteristics that reliably predict rhinogenic headache. MATERIALS AND METHOD: Of 356 patients who underwent nasal surgery between March and December 2009, 41 patients with headaches were enrolled in this prospective study. Clinical features of headache, such as onset, time of day, duration, frequency, nature, side and location, existence of aura, aggravating and relieving factors and accompanying nasal symptoms, underlying diseases, endoscopic findings, and computed tomography scans of the paranasal sinuses were evaluated. Headache intensity was graded based on a 10-point visual analog scale (VAS) pre- and post-operatively. RESULTS: The most common characteristics of rhinogenic headache included a stabbing or squeezing nature, frontal area location, accompanying nasal obstruction or rhinorrhea, and underlying sinusitis or septal deviation. The subjective intensity of the headache, measured using the VAS score, improved in 80% (33/41) of the patients after surgery. CONCLUSION: Nasal surgery should be considered when rhinogenic headache is suspected and there are definite nasal pathologies.

Absorbable Packing Materials in The Nasal Cavity Following Sinonasal Surgery

Recently, biomaterials for spacers following sinus surgery have been extensively researched. Such materials may reduce the incidence of early postoperative bleeding and formation of synechiae, and possibly promote mucosal healing. The aims of this study are to review recent advances in absorbent packing materials for the nasal cavity and to differentiate their effects on hemostasis, wound healing and prevention of adhesion.

Alternative technique for changing from nasal to oral endotracheal tube for orthognathic and nasal surgery by using an airway exchange catheter: a case report / 대한마취과학회지

A 28-year-old male patient with right maxillar, zygomatic arch, orbital wall, and nasal bone fractures had an orthognathic and nasal surgery. Naso-endotracheal intubation is the first choice during surgical correction of dentofacial deformities in an orthognathic surgery; however, its presence can interfere with concomitant surgical procedures on the nose. Traditionally, the naso-endotracheal tube will be removed and replaced with an oro-endotracheal tube. We changed the endotracheal tube from nasal to oral by using an airway exchange catheter.

Endoscopic Sinus Surgery and Septoplasty Performed Under Local Anesthesia: Comparative Analysis of Patient Discomfort

OBJECTIVES: The goal of this study is to compare the degree of patient discomfort between endoscopic sinus surgery (ESS) and septoplasty under local anesthesia. MATERIAL AND METHODS: A total 95 patients that underwent ESS and septoplasty under local anesthesia between July 2009 and January 2010 were enrolled in this study. The patients estimated the parameters of their own discomfort (pain, position, noise, anxiety, and memory). The score of each of the parameters ranged from 0 to 4. We compared the scores of the parameters between the ESS and septoplasty groups. RESULTS: Of the 95 patients, 61 (64%) received ESS, 32 (34%) received septoplasty, and 2 (2%) received both. The scores of all the parameters were not greater than moderate in both groups. There were no significantly statistical differences between the two groups. However, the ESS group had lower scores than the septoplasty group in the parameters of pain, position, noise, and memory. No remarkable complications occurred. CONCLUSION: The patients in this study had modest discomfort and no noticeable complications during the surgeries under local anesthesia. Although no statistical difference existed between the two groups, the ESS group experienced relatively lower discomfort levels during the surgery under local anesthesia compared to the septoplasty group.

Introduction: Epistaxis is by far the most common emergency complaint in otolaryngology. Its etiology is multifactorial, predominantly by traumatic causes. An alternative in surgical management of significant epistaxis cases, is the endoscopic cauterization or ligature of the sphenopalatine artery (SPA). Aim: This study aims to review the experience of the Hospital Clínico de la Universidad de Chile in the endoscopic management of patients with posterior epistaxis. Material and methods: The surgical records have been reviewed between the years 2007and 2011, considering all patients who were treated for posterior epistaxis, by endoscopic nasal surgery. Results: A total of 23 cases were reviewed. The average age of patients was 52 ± 18 years. 60% of patients had a history of hypertension in treatment. Clip ligature with electrocauterization of the SPA was performed in 52.1% of cases, clip ligature of the SPA in 26.2%%, and isolated electrocauterization of the SPA in 21.7%% of cases. Discussion and conclusions: Endoscopic treatment of posterior epistaxis is a simple and reproducible technique, being a safe and effective therapeutic tool for these patients.

Comparison of Parecoxib and Proparacetamol in Endoscopic Nasal Surgery Patients

PURPOSE: The aim of the study was to compare the efficacy of parecoxib for postoperative analgesia after endoscopic turbinate and sinus surgery with the prodrug of acetaminophen, proparacetamol. MATERIALS AND METHODS: Fifty American Society of Anesthesiology (ASA) physical status I-II patients, receiving functional endoscopic sinus surgery (FESS) and endoscopic turbinectomy, were investigated in a prospective, randomized, double-blind manner. After local infiltration with 1% mepivacaine, patients were randomly allocated to receive intravenous (IV) administration of either 40mg of parecoxib (n=25) or 2g of proparacetamol (n=25) 15 min before discontinuation of total IV anaesthesia with propofol and remifentanil. A blinded observer recorded the incidence and severity of pain at admission to the post anaesthesia care unit (PACU) at 10, 20, and 30 min after PACU admission, and every 1 h thereafter for the first 6 postoperative h. RESULTS: The area under the curve of VAS (AUC(VAS)) calculated during the study period was 669 (28-1901) cm·min in the proparacetamol group and 635 (26-1413) cm·min in the parecoxib group (p=0.34). Rescue morphine analgesia was required by 14 patients (56%) in the proparacetamol group and 12 patients (48%) in the parecoxib (p> or=0.05), while mean morphine consumption was 5-3.5mg and 5-2.0mg in the proparacetamol groups and parecoxib, respectively (p> or=0.05). No differences in the incidence of side effects were recorded between the 2 groups. Patient satisfaction was similarly high in both groups, and all patients were uneventfully discharged 24h after surgery. CONCLUSION: In patients undergoing endoscopic nasal surgery, prior infiltration with local anaesthetics, parecoxib administered before discontinuing general anaesthetic, is not superior to proparacetamol in treating early postoperative pain.

Effect of Controlled Hypotension by Nitroglycerin Combined with Smolol in Endoscopic Nasal Surgery / 医学研究杂志

Objective To evaluate the effect of controlled hypotension with nitroglycerin and esmolol in the operation of endoscopic nasal surgery.Methods 60 patients undergoing selective endoscopic nasal surgery were randomly divided into three groups averagely: control group (groupⅠ), controlled hypotension with nitroglycerin group(group Ⅱ), controlled hypotension with nitroglycerin and esmolol group (groupⅢ). Every group has 20 patients.Mean artery pressure (MAP), HR, scores of surgical field quality(SSFQ) were recorded before anaesthesia and 10,20,30,40 minutes after anaesthesia. After the operation, bleeding capacity, operation time and dosage of nitroglycerin were recorded too.Results The bleeding capacity and operation time in groupⅡ and Ⅲ was significantly less than that in groupⅠ(P
