Eventos adversos relacionados à sonda nasogástrica / nasoentérica em pacientes adultos: revisão integrativa da literatura / Adverse events related to the nasogastric / nasoenteral tube in adult patients: integrative literature review

Objetivo: trata-se de revisão integrativa da literatura realizada com o objetivo de identificar os estudos primários que abordam os eventos adversos relacionados à sonda nasogástrica / nasoentérica (SNG/SNE) em pacientes adultos. Método: a busca foi realizada no mês de abril de 2017 nas bases de dados PubMed, CINAHL, LILACS, EMBASE e Scopus. Para realizar a busca foram utilizadas palavras-chave e encontradas 1.020 citações. Destas, 988 artigos foram excluídos a partir da leitura de títulos e resumos. Em seguida, procedeu-se a leitura, na íntegra, de 32 artigos, dos quais 12 foram excluídos. Logo, um total de 20 artigos foram incluídos no estudo. Foi realizada, também, busca manual nas referências dos artigos incluídos com o intuito de encontrar estudos que não foram recuperados anteriormente nas bases de dados supracitadas. Foram obtidos 84 artigos, dos quais 30 foram excluídos, a partir da leitura de títulos e resumos. Dos 54 artigos recuperados, quatro foram excluídos após leitura na íntegra e um artigo durante a extração dos dados. Resultados: para esta revisão integrativa, foram incluídos um total de 69 artigos. Os dados foram analisados e posteriormente classificados em duas categorias principais que evidenciaram os eventos adversos relacionados ao uso de SNG/SNE: incidentes mecânicos (complicações respiratórias, complicações no esôfago ou faringe, obstrução da sonda, perfuração intestinal, perfuração intracraniana e saque não planejado da sonda) e outros incidentes (lesão por pressão relacionada à fixação e conexão errada). A maior parte dos artigos recuperados foi incluída na subcategoria "complicações respiratórias" devido ao posicionamento inadequado da extremidade distal da sonda no trato respiratório, o que resultou em pneumotórax e/ou óbito. Outros eventos adversos estavam relacionados à obstrução da sonda, perda da mobilidade das cordas vocais, perfuração intestinal com consequente infecção, lesão na pele e mucosas, e queimadura corporal devido à desconexão. Conclusão: os resultados sintetizados nesta revisão permitem que os profissionais da saúde, especialmente os da enfermagem, reflitam sobre a segurança dos pacientes em uso de SNG/SNE e que repensem a maneira como as sondas estão sendo manuseadas na prática clínica

Objective: an integrative literature review was developed to identify the primary studies on the adverse events related to nasogastric / nasoenteral tubes (NGT/NET) in adult patients. Method: the search was undertaken in April 2017 in the databases PubMed, CINAHL, LILACS, EMBASE and Scopus. Keywords were used for the search and 1,020 citations were found. After reading titles and abstract, 988 of these articles were excluded. Next, 32 articles were fully read, 12 of which were excluded. Hence, in total, 20 articles were included in the study. In addition, a manual search was undertaken in the references of the included articles, aiming to find studies that had not been retrieved earlier in the abovementioned databases. Eighty-four articles were found, 30 of which were excluded after reading the titles and abstracts. Of the 54 retrieved articles, four were excluded after reading the full version and one article during the extraction of the data. Results: for this integrative review, in total, 69 articles were included. The data were analyzed and then classified in two main categories that evidenced the adverse events related to the use of NGT/NET: mechanic incidents (respiratory complications, esophageal or pharyngeal complications, tube obstruction, intestinal perforation, intracranial perforation and unplanned tube withdrawal) and other incidents (wrong connection and fixationrelated pressure ulcer). Most of the articles were included in the subcategory "respiratory complications" due to improper positioning of the distal end of the tube in the respiratory tract, resulting in pneumothorax and/or death. Other adverse events were related to tube obstruction, loss of vocal chord mobility, intestinal perforation with consequent infection, skin and mucous membrane ulcers, and body burns due to detachment. Conclusion: based on the results synthesized in this review, health professionals, especially in nursing, can reflect on the safety of patients using NGT/NET and reconsider the manipulation of the tubes in clinical practice

Comparison of different methods of nasogastric tube insertion in anesthetized and intubated patients / Comparação de diferentes métodos de inserção de sonda nasogástrica em pacientes anestesiados e intubados

Abstract Background Nasogastric tube insertion may be difficult in anesthetized and intubated patients with head in the neutral position. Several techniques are available for the successful insertion of nasogastric tube. The primary aim of this study was to investigate the difference in the first attempt success rate of different techniques for insertion of nasogastric tube. Secondary aim was to investigate the difference of the duration of insertion using the selected technique, complications during insertion such as kinking and mucosal bleeding. Material and methods 200 adult patients, who received general anesthesia for elective abdominal surgeries that required nasogastric tube insertion, were randomized into four groups: Conventional group (Group C), head in the lateral position group (Group L), endotracheal tube assisted group (Group ET) and McGrath video laryngoscope group (Group MG). Success rates, duration of insertion and complications were noted. Results Success rates of nasogastric tube insertion in first attempt and overall were lower in Group C than Group ET and Group MG. Mean duration and total time for successful insertion of NG tube in first attempt were significantly longer in Group ET. Kinking was higher in Group C. Mucosal bleeding was statistically lower in Group MG. Conclusion Use of video laryngoscope and endotracheal tube assistance during NG tube insertion compared with conventional technique increase the success rate and reduce the kinking in anesthetized and intubated adult patients. Use of video laryngoscope during nasogastric tube insertion compared to other techniques reduces the mucosal bleeding in anesthetized and intubated adult patients.

Resumo Justificativa A inserção de sonda nasogástrica (NG) pode ser difícil em pacientes anestesiados e intubados com a cabeça em posição neutra. Há várias técnicas para a inserção bem-sucedida de sonda NG. O objetivo primário deste estudo foi investigar a diferença da taxa de sucesso na primeira tentativa de diferentes técnicas para inserção de sonda NG. O objetivo secundário foi investigar a diferença do tempo de inserção com o uso da técnica selecionada e as complicações durante a inserção (dobradura da sonda e sangramento da mucosa). Material e métodos 200 pacientes adultos que receberam anestesia geral para cirurgias abdominais eletivas que exigiam inserção de sonda NG foram randomicamente distribuídos em quatro grupos: grupo convencional (Grupo C), grupo com a cabeça posicionada lateralmente (Grupo L), grupo com assistência de tubo traqueal (Grupo TE) e grupo com videolaringoscópio McGrath (grupo MG). As taxas de sucesso, os tempos de inserção e as complicações foram registrados. Resultados As taxas de sucesso de inserção da sonda NG na primeira tentativa e em geral foram menores no Grupo C do que nos grupos TE e MG. As durações e os tempos totais de inserção bem-sucedida da sonda NG na primeira tentativa foram significativamente maiores no Grupo TE. Dobradura foi maior no Grupo C. Sangramento da mucosa foi estatisticamente menor no Grupo MG. Conclusão O uso de videolaringoscópio e de TE durante a inserção de sonda NG comparado com o uso da técnica convencional aumentou a taxa de sucesso e reduziu a dobradura da sonda em pacientes adultos anestesiados e intubados. O uso de videolaringoscópio durante a inserção de sonda NG em comparação com outras técnicas reduz o sangramento da mucosa em pacientes adultos anestesiados e intubados.

Nosocomial pneumonia: risk factors, rates and trends

This study aimed to estimate the rate of and risk factors for nosocomial pneumonia of patients admitted to hospitals in Taif, Saudi Arabia. A case-control study was conducted of 211 discharged patients with confirmed pneumonia and 633 controls without pneumonia and a review was made of hospital records during 1999-2003. Multiple logistic regression showed that duration of hospital stay, unit of admission, chronic obstructive pulmonary diseases, coma, nasogastric tube, endotracheal tube, debilitating diseases and mechanical ventilation were independently associated with increased risk of pneumonia. The mean incidence of overall nosocomial infection in the period 1999-2003 was 3 per 100 discharged patients, while the mean incidence of nosocomial pneumonia was 0.88

Comparison of the efficacy between lidocaine spray plus lidocaine jelly lubrication and lidocaine jelly lubrication alone prior to nasogastric intubation: a prospective double-blind randomized controlled study.

OBJECTIVE: Although a common procedure, nasogastric (NG) intubation is also painful and unsatisfactory. Previous studies showed the benefits of local anesthesia in various forms over lubricant jelly alone, but they are rarely used due to their inconvenience and unavailability. The authors conducted a double-blind randomized controlled study to compare a commercial-available 10% lidocaine spray plus 2% lidocaine jelly lubrication and 2% lidocaine jelly lubrication alone prior to NG intubation. MATERIAL AND METHOD: Patients who fulfilled the indications for NG intubation were randomized to receive either 10% lidocaine spray or placebo (normal saline) spray to the nostril and throat prior to NG intubation. NG tubes lubricated with 2% lidocaine jelly were then inserted by experienced physicians. Physician, who sprayed, inserted the NG tubes and collected the patient's data, did not know the content of the spray, while patients were also blinded against the information of the spray. RESULTS: Sixty patients were included in the present study. Thirty one randomly received lidocaine spray and 29 received placebo spray. There were more female patients in the lidocaine group (65% vs. 28%, p=0.04), but ages, indications for NG intubation, size of NG tube, and physicians' experience in the procedure were similar in both groups. Patients' discomfort after being sprayed was also similar in both groups. However during the NG intubation, the patients in the lidocaine group experienced less pain as measured by visual analog scale (23.6 +/- 16.6 vs. 43.1 +/- 31.4 mm, p=0.005) and less discomfort (30.0 +/- 24.4 vs. 51.4 +/- 30.0 mm, p=0.004) than the placebo group. Ninety-three percent of the patients in the lidocaine group favored the same spray for their next intubations, while 65% of the placebo group did (p = 0.009). In addition, there was more physicians' satisfaction in the lidocaine group as measured by 5-point Likert scale (p=0.041). Likewise, 61% of the physicians favored lidocaine spray compared to 34.5% of the placebo spray (p=0.038). Degree of difficulty, duration of intubation, number of attempts and success rates of NG intubations were as well similar in both groups. No complications were found in the present study. CONCLUSION: 10% lidocaine spray plus 2% lidocaine jelly lubrication was more effective in relieving patients' pain, discomfort, and resulted in higher physicians' satisfaction. There were also no additional side effects as compared to 2% lidocaine jelly lubrication alone. Therefore, it should be recommended for routine application.

The Effects of Swallowing with Oropharyngeal Sensory Stimulation in Nasogastric Tube Insertion in Stroke Patients / 간호학회지

PURPOSE: This study was to identify the effects of oropharyngeal sensory stimulation on a functional oral intake scale, oro-pharyngeal swallowing functions, and aspiration pneumonia symptoms with nasogastric tube insertion in stroke patients. METHOD: This study was a nonequivalent control group non-synchronized design. The subjects of the study were 32 patients who were hospitalized in Kosin Gaspel hospital. The experimental subjects were stimulated for 10~20 minutes, 1 time per day. The intervention was implemented for 2 weeks. RESULT: Participants in the experimental group significantly received a higher score in oro-pharyngeal swallowing function than those in the control group. However the participants in the experimental group only got a high score in the function oralintake scale which doesn't imply a statistical significance. In addition, they didn't geta remarkably higher score in aspiration pneumonia symptoms than those in the control group. CONCLUSION: This study demonstrates that oropharyngeal sensory stimulation is effective in promoting recovery oro-pharyngeal swallowing function of nasogastric tube insertions in stroke patients.

Cómo realizar una evaluación de deglución completa, eficaz y en corto tiempo / How to make a complete, efficient and short-time evaluation of deglution

El trastorno de deglución es una patología que va en aumento en los pacientes hospitalizados. El estudio y manejo de esta condición tiene muchas alternativas según la bibliografía. Analizamos las interconsultas para evaluación de deglución enviadas a nuestro servicio entre el 1 de enero al 31 de diciembre de 2004. Se confeccionó un protocolo con los antecedentes y el examen realizado y se clasificó a los pacientes según la severidad del trastorno observado ingresando así a un algoritmo diseñado para continuar su terapia y seguimiento. Este trabajo pudo comprobar la alta incidencia del trastorno de deglución en pacientes hospitalizados; que correspondió al 20 por ciento del total de interconsultas del Servicio. Las dos causas más frecuentes para este trastorno fueron: accidente vascular en un 56 por ciento e intubación prolongada en un 58 por ciento; algunos pacientes presentaban ambos diagnósticos. Los resultados mostraron que los factores que más se relacionaban con un trastorno de deglución severo eran: sexo masculino, limpieza oral incompleta, manejo anormal de la saliva, movilidad palatina anormal, saliva moviéndose libremente en glotis, disminución de la sensibilidad en la glotis, restos en seno piriforme y ahogo al comer. Se propone un protocolo de evaluación de deglución para este tipo de pacientes acorde a nuestra experiencia como Servicio de Otorrinolaringología.

Gastric perforation in neonates: Analysis of five cases

Neonatal gastric perforation has always been a mysterious entity regarding its cause. Although some have definite causes e.g. TOP causing severe dilatation of the stomach, iatrogenic secondary to the introduction of a hard nasogastric tube but the majority have no obvious reasons. Many theories have been advocated such as gastric ischemia or aerophagia due to excessive crying. The common feature in the five cases seen at Maadi Military hospital over a period of 5 years was marked abdominal distension causing dyspnea, fortunately, all of them survived. This good survival rate in our opinion was due to the good pre and postoperative care as well as the lack of sepsis oftenly encountered with gastric juice leakage

Unusual presentation of an iatrogenic esophageal perforation in a newborn.

Spontaneous rupture of esophagus (Boerhaave's Syndrome) in neonates is a rare occurrence. However iatrogenic perforation of the esophagus is not that uncommon, especially in a premature. The presentation of esophageal perforation is rather stereotyped. In the present case however patient presented with unusual features.

Inadvertent insertion of nasogastric tube into the brain.

An unusual case of a nasogastric (Ryle's) tube inserted in the brain in a patient having severe head injury with skull base fractures is reported here along with a brief review of literature. A 35 years male was referred from a peripheral institute following head trauma with endotracheal tube and nasogastric tube in situ. A CT scan of the brain showed multiple skull base fractures and a high parietal extradural hematoma. It also revealed that the nasogastric tube had inadvertently found its way into the brain through the lamina cribrosa of the ethmoid bone. The tube was removed under aseptic conditions in the operation theatre but the patient expired on day 2 of admission due to the head injuries sustained.

Clinical Implications of the Glucose Test Strip Method for Early Detection of Pulmonary Aspiration in Nasogastric Tube- Fed Patients / 간호학회지

PURPOSE: This study was performed to test the clinical usefulness of the glucose test strip method for early detection of pulmonary aspiration in tube fed patients. METHOD: The subjects for the study were 36 patients who were receiving enteral feedings and 39 patients who were not given enteral feedings. For the analysis, the tube fed patients were divided into two groups (clinically significant aspiration and no aspiration) according to criteria. RESULT: The mean glucose concentration of tracheal secretions from non enteral fed patients was 26.35mg/dl and were lower than those concentrations found in tube fed patients (32.75mg/dl). The mean glucose concentration of the aspiration group was 45.60mg/dl and the glucose concentration of the non aspiration group was 19.93mg/dl. The difference was statistically significant (t=2.163, p=. 038). More subjects in the no aspiration group (73%) than the aspiration group (56%) had glucose concentrations below 20mg/dl. After deleting the cases that had samples containing blood, glucose concentrations of tracheal aspirates were lower in both groups. CONCLUSION: The glucose level of the aspiration group was significantly lower than the no aspiration group and more subjects in the aspiration group had a glucose level higher than 101mg/dl. Therefore, the glucose test of tracheal secretions in tube fed patients could be a desirable test for screening for tracheal aspiration. Especially the patient who is showing repeatedly high glucose levels should not be given feedings until reassessment is completed.

Sonda nasoenteral, aspiração traqueal e pneumonia aspirativa em pacientes hospitalizados com doença cérebro-vascular complicada por disfagia orofaríngea / Nasogastric feeding tube, aspiration and aspiration pneumonia in hospitalized stroke patients with oropharyngeal dysphagia

Racional - Estima-se que dentre os 300.000 a 600.000 indivíduos com doenças neurológicas que são afetados por disfagia orofaríngea nos Estados Unidos todos os anos, 37% deles desenvolverão pneumonia aspirativa, e 3,8% morrerão, se não fizerem parte dos programas de diagnósticos e tratamento da disfagia orofaríngea. Objetivo - Verificar a associação da presença da sonda nasoenteral com aspiração e pneumonia aspirativa, em pacientes com doença cerebrovascular, complicada por diafagia orofaríngea. Casuística e Método - Foram estudados 123 pacientes com disfagia orofaríngea comprovada por exames instrumentais (estudo endoscópico da deglutição FEES e videofluoroscopia da deglutição), que foram realizados em todos os pacientes. Eles foram acompanhados por seis meses, e neste período PA foi diagnosticado em 36 deles. Resultados - Os pacientes com sonda nasoenteral apresentaram maior freqüência de pneumonia aspirativa e de aspiração do que os sem sonda (P=0,0001 e P=0,048, respectivamente). Conclusão - Os pacientes com doença cerebrovascular complicados por disfagia e portadores de sondas nasoenterais promovem acúmulo de secreções na faringe e aumento do ph intragástrico com conseqüente colonização bacteriana. Esta situação aumenta o risco de aspiração e pneumonia. O seu uso deveria ser restrito e bem indicado.

Relationship between Esophageal Lesions Observed by Endoscopy and Nasogastric Intubation: A Study of 185 Cases of Percutaneous Endoscopic Gastrostomy / 대한소화기학회지

BACKGROUND/AIMS: Percutaneous endoscopic gastrostomy (PEG) is a method widely used for long-term enteral nutrition in dysphagia. Mostly, it is preceded by nasogastric intubation (NI) for short-term enteral nutrition; endoscopic findings associated with NI are encountered during PEG. The purpose of this study was to discuss such findings and to delineate a relationship between these findings, especially esophageal lesions and the duration of NI. METHODS: This study involved 185 individuals who had undergone PEG at Kyung Hee Medical Center from January 1999 to May 2002. The medical records were examined retrospectively. RESULTS: The dysfunction of the CNS comprised 98.4% of the causes of dysphagia. The duration of NI was 15.2 weeks on average, with median value of 8.7 weeks, indicating that PEG was performed relatively soon. Endoscopic findings revealed esophagitis in 63 cases, esophageal ulcers in 27 and active bleedings in another 10. The incidence of esophageal lesions was shown to be higher in subjects with duration of NI under 12 weeks than in those with duration over 12 weeks (p=0.032). CONCLUSIONS: PEG was carried out in many cases during the early stages of dysphagia, and NI-associated esophageal lesions appeared to be more prevalent within 12 weeks of NI duration. These results may be of help in deciding the timing of PEG.
