RESUMO
Background: Surgical care has a role in treating a broad spectrum of diseases in the alleviation of human suffering. Upper abdominal surgery included gastrectomy, pancreatectomy, hepatic resection, cholecystectomy and splenectomy. Maximal inspiratory pressure (Pimax) is an important indicator for assessing the strength of inspiratory muscles. Respiratory muscle training devices enhance respiratory muscle strength, endurance and exercise capacity. Pressure Threshold IMT devices are usually handheld devices with a spring load that is impeded with different intensities. Incentive Spirometer is a form of ventilatory training that emphasis sustained maximum inspiration. Therefore, the present study aims to assess the effect of Threshold Inspiratory Muscle Training versus Incentive spirometry in participants with upper abdominal surgeries. Materials and Methods: A prospective cross-sectional comparative study was done with 30 participants with upper abdominal surgeries in the age group of 20 to 65. On Day 1 and after 2 weeks the maximal inspiratory pressure was measured using Hand Held Pressure Manometer Device (Pimax). Group A participants received Threshold Inspiratory Muscle Training (IMT) and Group B participants received Incentive spirometry. The intervention was given for 5 days in a week for 2 weeks. The duration for each session was of 15-30 minutes which also includes rest periods. Data was analyzed using student Paired ‘t’ test and Unpaired ‘t’ test. Result: There was extremely significant difference (p<0.0001) in Maximal Inspiratory Pressure (Pimax) in both the groups but Group A showed slightly more improvement were Threshold Inspiratory Muscle Training (IMT) was given as an intervention after 2 weeks. Conclusion: The study shows extremely significant improvement in Maximal Inspiratory Pressure (PImax) in both the groups. This study concluded that Threshold IMT has more effect than Incentive Spirometry in participants with upper abdominal surgeries.
RESUMO
Objective:To evaluate the effect of threshold inspiratory muscle training (TIMT) on respiratory muscle strength and clinical outcomes for machinery ventilates patients. Methods:The Cochrane Library, PubMed, Embase, Web of Science, CBM, Wanfang Database, CNKI and VIP were searched for the randomized controlled trials (RCT) about the effect of TIMT on respiratory muscle strength and clinical outcomes from establishment to July 1st, 2018. Two researchers strictly evaluated literature quality and extracted information, and then a Meta-analysis was carried out. Results:A total of 14 literatures were included with 650 patients, 323 cases in the experimental group and 327 cases in the control group. Compared with the control group, the massive inspiratory pressure (MIP) increased (MD = -6.65, 95%CI -8.27~-5.03, P < 0.001), the respiratory muscle strength increased (MD = -5.04, 95%CI -7.68~-2.04, P = 0.0002), the weaning time reduced (MD = -1.01, 95%CI -1.65~-0.37, P = 0.002), the mechanical ventilation time shortened (MD= -2.24, 95%CI -4.33~-0.15, P = 0.04), as well as the intensive care unit (ICU) length of stay (MD= -3.41, 95%CI -6.06~-0.76, P= 0.01). There was no significant difference in maximum expiratory pressure (MEP) (MD= 1.22, 95%CI -6.55~9.00, P = 0.76), the rate of reintubation/tracheotomy (RR = 0.99, 95%CI 0.56~1.73, P = 0.96) and mortality (RR= 1.05, 95%CI 0.53~2.06, P = 0.89) between two groups. Conclusion:TIMP could improve MIP and respiratory muscle strength of patients with mechanical ventilation, shorten the weaning time, the mechanical ventilation time and the ICU length of stay, and then reduce the incidence of weaning failure.
