Terapia de oxigenación hiperbárica en el tratamiento del dolor / Hyperbaric oxygenation therapy in pain treatment

El dolor crónico constituye un reto terapéutico especial. Se presenta una revisión narrativa sobre el papel del tratamiento de oxigenación hiperbárica (TOHB) en el tratamiento del dolor neuropático, y sus aplicaciones en dolor crónico, síndromes neurosensitivos disfuncionales y oncodolor. El conocimiento de las indicaciones de TOHB en algiología y su aplicación en la práctica médica puede contribuir a mejorar la calidad de vida del paciente. (AU)

Chronic pain represents a special therapeutic challenge. We present a narrative review on the role of Hyperbaric Oxygen Therapy (HBOT) in the treatment of neuropathic pain, and its applications in chronic pain, dysfunctional neurosensitive syndromes and oncological pain. The knowledge of the indications of HBOT in algiology and its application in medical practice can contribute to improve the quality of life of the patient. (AU)

The place of hyperbaric oxygen therapy and ozone therapy in sudden hearing loss / O papel da oxigenoterapia hiperbárica e da ozonioterapia na surdez súbita

Abstract Introduction: It is difficult to evaluate the effect of drugs clinically used for idiopathic sudden sensorineural hearing loss, mainly because its underlying mechanism remains unknown. Objective: This study assessed the efficacy of hyperbaric oxygen therapy or ozone therapy in the treatment of idiopathic sudden sensorineural hearing loss, when either therapy was included with steroid treatment. Methods: A retrospective analysis examined 106 patients with idiopathic sudden sensorineural hearing loss seen between January 2010 and June 2012. Those with an identified etiology were excluded. The patients were divided into three treatment groups: oral steroid only (n = 65), oral steroid + hyperbaric oxygen (n = 26), and oral steroid + ozone (n = 17). Treatment success was assessed using Siegel criteria and mean gains using pre- and post-treatment audiograms. Results: The highest response rate to treatment was observed in the oral steroid + ozone therapy group (82.4%), followed by the oral steroid + hyperbaric oxygen (61.5%), and oral steroid groups (50.8%). There were no significant differences in the response to treatment between the oral steroid and oral steroid + hyperbaric oxygen groups (p < 0.355). The oral steroid + ozone group showed a significantly higher response rate to treatment than the oral steroid group (p = 0.019). There were no significant differences between the oral steroid + hyperbaric oxygen and oral steroid + ozone groups (p = 0.146). Conclusion: The efficiency of steroid treatment in patients with severe hearing loss was low. It was statistically ascertained that adding hyperbaric oxygen or ozone therapy to the treatment contributed significantly to treatment success.

Resumo Introdução: É difícil avaliar o efeito dos fármacos clinicamente usados na surdez súbita idiopática, principalmente porque o seu mecanismo subjacente se mantém desconhecido. Objetivo: Avaliar a eficácia da oxigenoterapia hiperbárica ou ozonioterapia no tratamento de surdez súbita, quando uma ou outra terapia é incluída no tratamento com esteroides. Método: Uma análise retrospectiva examinou 106 pacientes com surdez súbita atendidos entre janeiro de 2010 e junho de 2012. Aqueles com uma etiologia identificada foram excluídos. Os pacientes foram divididos em três grupos de tratamento: apenas esteroide oral (n = 65), esteroide por via oral + oxigenoterapia hiperbárica (n = 26) e esteroides por via oral + ozônio (n = 17). O sucesso do tratamento foi avaliado com critérios de Siegel e os ganhos médios com audiogramas pré e pós-tratamento. Resultados: A taxa de resposta mais elevada para o tratamento foi observada no grupo de esteroide + ozonioterapia (82,4%), seguida por grupos de esteroide oral + oxigenoterapia hiperbárica (61,5%) e esteroide oral (50,8%). Não houve diferenças significantes na resposta ao tratamento entre os grupos de esteroide oral e esteroides + oxigenoterapia hiperbárica (p < 0,355). O grupo de esteroide oral + ozônio apresentou uma taxa de resposta significantemente mais elevada ao tratamento do que o grupo de esteroide oral (p = 0,019). Não houve diferenças significantes entre os grupos de esteroide oral + oxigenoterapia hiperbárica e esteroide oral + ozônio (p = 0,146). Conclusão: A eficiência do tratamento com esteroides em pacientes com perda auditiva grave foi baixa. Verificou-se estatisticamente que a adição de oxigenoterapia hiperbárica ou ozonioterapia ao tratamento contribuiu significantemente para o sucesso do tratamento.

Hyberbaric oxygen as sole treatment for severe radiation - induced haemorrhagic cystitis

ABSTRACT Purpose To examine the safety and efficacy of hyperbaric oxygen as the primary and sole treatment for severe radiation-induced haemorrhagic cystitis. Materials and methods Hyperbaric oxygen was prospectively applied as primary treatment in 38 patients with severe radiation cystitis. Our primary endpoint was the incidence of complete and partial response to treatment, while the secondary endpoints included the duration of response, the correlation of treatment success-rate to the interval between the onset of haematuria and initiation of therapy, blood transfusion need and total radiation dose, the number of sessions to success, the avoidance of surgery and the overall survival. Results All patients completed therapy without complications with a mean follow-up of 29.33 months. Median number of sessions needed was 33. Complete and partial response rate was 86.8% and 13.2%, respectively. All 33 patients with complete response received therapy within 6 months of the haematuria onset. One patient needed cystectomy, while 33 patients were alive at the end of follow-up. Conclusions Our study suggests the early primary use of hyperbaric oxygen for radiation-induced severe cystitis as an effective and safe treatment option.

Adjunctive Hyperbaric Oxygen Therapy promotes successful healing in patients with refractory Crohn's disease

PURPOSE: To investigate de adjunctive effect of Hyperbaric Oxygen Therapy in a group of patients with refractory Crohn's disease. METHODS: A total of 29 subjects with refractory Crohn's disease were submitted to daily sessions of Hyperbaric Oxygen Therapy, in a 2800 Sechrist Monoplace Hyperbaric Chamber (Sechrist, USA) pressurized to 2.4 ATA. Each session lasted 2 hours. The endpoint was closure of enterocutaneous fistulas and complete healing of Pyoderma Gangrenosum and perineal Crohn's disease. RESULTS: A total of 829 HBOT sessions were performed and no complications were noted. Overall success rate was 76% (22 cases). Pyoderma Gangrenosum and enterocutaneous fistulas had the highest successful healing rates (100% and 91%, respectively). Perineal Crohn's disease healing rate was 65%. CONCLUSION: Adjunctive Hyperbaric Oxygen Therapy promoted satisfactory healing in a group of patients with refractory Crohn's disease.

Is there a role for hyberbaric oxygen as primary treatment for grade IV radiation-induced haemorrhagic cystitis? a prospective pilot-feasibility study and review of literature

Purpose To examine the safety and efficacy of hyperbaric oxygen as the primary treatment for Grade IV radiation-induced haemorrhagic cystitis. Materials and Methods Hyperbaric oxygen was prospectively applied as a primary treatment option in 11 patients with Grade IV radiation cystitis. Primary endpoint was the incidence of complete and partial response to treatment. Secondary endpoints included the duration of response, the correlation of treatment success-rate to the interval between the onset of haematuria and initiation of therapy, blood transfusion need and total radiation dose, the number of sessions to success, the avoidance of surgery and the overall survival. Results All patients completed therapy without complications for a mean follow-up of 17.82 months (range 3 to 34). Mean number of sessions needed was 32.8 (range 27 to 44). Complete and partial response rate was 81.8% and 18.2%, respectively. However, in three patients the first treatment session was not either sufficient or durable giving a 72.7% rate of durable effect. Interestingly, all 9 patients with complete response received therapy within 6 months of the haematuria onset compared to the two patients with partial response who received therapy at 8 and 10 months from the haematuria onset, respectively (p = 0.018). The need for blood transfusion (p = 0.491) and the total radiation dose (p = 0.259) were not correlated to success-rate. One patient needed cystectomy, while all patients were alive at the end of follow-up. Conclusions Early primary use of hyperbaric oxygen to treat radiation-induced grade IV cystitis is an effective and safe treatment option. .
