Comparison of Diaphragmatic Breathing Exercise, Volume and Flow Incentive Spirometry, on Diaphragm Excursion and Pulmonary Function in Patients Undergoing Laparoscopic Surgery: A Randomized Controlled Trial

Effect of adding diaphragmatic breathing to corrective exercises on kyphotic angle and diaphragmatic excursion in postmenopausal kyphotic women: A randomized controlled trial

BACKGROUND

Age-related thoracic kyphosis can impair posture, diaphragmatic excursion, respiratory function, and overall quality of life (QoL).

PURPOSE

This randomized controlled trial aimed to compare the effects of corrective exercises alone versus combined with diaphragmatic breathing exercises on thoracic kyphosis, diaphragmatic excursion, thoracic pain, and QoL in postmenopausal kyphotic women.

METHODS

Forty postmenopausal women diagnosed with thoracic kyphosis were randomly divided into two groups. Group A received corrective exercises for 12 weeks (n = 20), while Group B received both diaphragmatic breathing exercises and corrective exercises for the same duration (n = 20). Primary outcome measures were thoracic kyphosis angle and diaphragmatic excursion, while secondary outcome measures were thoracic pain and QoL. Both groups were assessed pre- and post-intervention using a flexible curve ruler for the thoracic kyphosis angle, ultrasonography for the diaphragmatic excursion, the visual analog scale for thoracic pain, and the Arabic version of the QoL Questionnaire of the European Foundation for Osteoporosis for QoL.

RESULTS

Both groups showed significant within-group improvements in all measures post-intervention (p < 0.05). Between-group comparisons post-intervention revealed no significant differences (p > 0.05) except for diaphragmatic excursion, where Group B showed significantly greater improvement (p < 0.05).

CONCLUSIONS

A 12-week program of corrective exercises alone or combined with diaphragmatic breathing exercises significantly improved kyphosis angle, thoracic pain, and QoL in postmenopausal kyphotic women. The addition of diaphragmatic breathing exercises provided further benefits by increasing diaphragmatic excursion to a greater degree compared with corrective exercises alone.

Is Incentive Spirometry Superior to Standard Care in Postoperative Cardiac Surgery on Clinical Outcomes and Length of Hospital and Intensive Care Unit Stay? A Systematic Review with Meta-Analysis

INTRODUCTION

Cardiac surgery is a frequent surgical procedure and may present a high risk of complications. Among the prophylactic strategies studied to decrease the rates of negative outcomes, respiratory care seems to reduce pulmonary complications. Incentive spirometry (IS) is a low-cost, respiratory exercise technique, used for the prevention and treatment of postoperative pulmonary complications (PPC). The aim of this review was to evaluate whether IS is superior to respiratory care, mobilization exercises, and noninvasive ventilation on PPC, and clinical outcomes.

METHODS

Systematic review. Medical Literature Analysis and Retrieval System Online (or MEDLINE®), Embase®, Cochrane Central Register of Controlled Trials (or CENTRAL), Physiotherapy Evidence Database (or PEDro), Cumulative Index of Nursing and Allied Health (or CINAHL®), Latin American and Caribbean Health Sciences Literature (or LILACS), Scientific Electronic Library Online (or SciELO), Allied, Scopus®, and OpenGrey databases, clinical trial registration sites, conferences, congresses, and symposiums were searched.

RESULTS

Twenty-one randomized trials and one quasi-randomized trial (1,677 participants) were included. For partial pressure of oxygen (PaO2), IS was inferior to respiratory care (mean difference [MD] -4.48; 95% confidence interval [CI] -8.32 to -0.63). Flow-oriented IS was inferior to respiratory care on PaO2 (MD -4.53; 95% CI -8.88 to -0.18). However, compared to respiratory care, flow-oriented IS was superior on recovery vital capacity.

CONCLUSIONS

This meta-analysis revealed that IS was not superior to standard respiratory care for PPCs and clinical outcomes, therefore its use should not be widely recommended until further studies with high quality be performed to ensure this clinical guidance.

Pulmonary function and complication prevention: A randomized controlled trial on lung expansion modalities of older adults undergoing upper abdominal surgery

Postoperative pulmonary complications (PPCs) are a major catastrophic consequence of upper abdominal surgery, resulting in morbidity and mortality. Therefore, the study aims to assess the effect of lung expansion modalities (LEMs) on older adults' pulmonary function and the incidence of pulmonary complications. The study randomly allocated 80 older adults (40 cases and 40 controls). Pulmonary function testing revealed a significant improvement in the study group's forced expiratory volume in one second, sixth second, and oxygen saturation on the fifth postoperative day (POD) compared to the first day [55.23%, 38.41%, and 2.87%; P0.001]. The reported PPCs incidence of the intervention group was less than the control group (15% and 30% on the third POD; 15% and 37.5% on the fifth POD). In conclusion, LEMs provide practical enhancement for the postoperative care of older adults by reducing PPCs by restoring measured pulmonary volumes.

Comparing the Effect of Incentive Spirometry and Deep Breathing Exercises on the Level of Shoulder Pain and Nausea Following Laparoscopic Cholecystectomy Surgery: A Clinical Trial Study

Cholecystitis treated by laparoscopy results in patients experiencing shoulder pain and nausea. Thus, the aim of the present study was to compare the effect of incentive spirometry and deep breathing exercises on the level of shoulder pain and nausea following laparoscopy. In this clinical trial, 105 patients were enrolled into three groups: use of incentive spirometry, deep breathing exercises, and control. Data were collected using a checklist and a visual analog scale and analyzed through the χ2, the Kruskal-Wallis, the Friedman, and the paired t test by SPSS Version 25. In the deep breathing exercise, incentive spirometry, and control groups, mean pain scores immediately after surgery but within 24 hours following the intervention were 3.8, 2.6, and 4.4, respectively. The mean score of severity of nausea for patients in the deep breathing exercise and incentive spirometry groups showed a significant difference immediately after the procedure, as well as at 12 and 24 hours post-intervention. Breathing exercises and incentive spirometry can be effective in reducing pain and nausea in patients undergoing cholecystectomy through laparoscopy. Because of the effectiveness of the two methods, nurses can use incentive spirometery and deep breathing exercises to diminish patients' pain post-cholecystectomy.

Volume Incentive Spirometry Reduces Pulmonary Complications in Patients After Open Abdominal Surgery: A Randomized Clinical Trial

Objective

To compare the effect of diaphragmatic breathing and volume incentive spirometry (VIS) on hemodynamics, pulmonary function, and blood gas in patients following open abdominal surgery under general anesthesia.

Methods

A total of 58 patients who received open abdominal surgery were randomly assigned to the control group (n=29) undergoing diaphragmatic breathing exercises and the VIS group (n=29) undergoing VIS exercises. All the participants performed the six-minute walk test (6MWT) preoperatively to evaluate their functional capacity. Hemodynamic indexes, pulmonary function tests, and blood gas indexes were recorded before surgery and on the 1st, 3rd, and 5th postoperative day.

Results

The functional capacity was not significantly different between the two groups during the preoperative period (P >0.05). At 3 days and 5 days postoperatively, patients in the VIS group had a significantly higher SpO2 than that in the control group (P <0.05). Pulmonary function test values were reduced in both two groups postoperatively when compared to the preoperative values but improved for three and five days afterward (P <0.05). Of note, the significantly elevated levels of peak expiratory flow (PEF), forced expiratory volume in the first second (FEV1), forced vital capacity (FVC), and FEV1/FVC ratio were observed on the 1st, 3rd, and 5th postoperative days in the VIS group compared with those in the control group (P <0.05). Besides, bass excess (BE), and pH values were significantly higher in the VIS group on the 1st postoperative day than those in the control group (P <0.05).

Conclusion

Diaphragmatic breathing and VIS could improve postoperative pulmonary function, but VIS exercise might be a better option for improving hemodynamics, pulmonary function, and blood gas for patients after open abdominal surgery, hence lowering the incidence of postoperative pulmonary complications.

The fully engaged inspiratory muscle training reduces postoperative pulmonary complications rate and increased respiratory muscle function in patients with upper abdominal surgery: a randomized controlled trial

BACKGROUND

Upper abdominal surgical treatment may reduce respiratory muscle function and mucociliary clearance, which might be a cause of postoperative pulmonary complications (PPCs). Threshold inspiratory muscle training (IMT) may serve as an effective modality to improve respiratory muscle strength and endurance in patients. However, whether this training could help patients with upper abdominal surgery remains to be determined. The aim of the present investigation was to determine the effect of a fully engaged IMT on PPCs and respiratory function in patients undergoing upper abdominal surgery. We hypothesized that the fully engaged IMT could reduce PPCs and improve respiratory muscle function in patients with upper abdominal surgery.

METHODS

This is a randomized controlled trial (RCT) with 28 patients who underwent upper abdominal surgery. Patients were randomly assigned to the control (CLT) group or the IMT group. The CTL group received regular health care. The IMT group received 3 weeks of IMT with 50% of MIP as the initial intensity before the operation. The intensity of MIP increased by 5-10% per week. The IMT was continued for 4 weeks after the operation. The study investigated the outcomes including PPCs, respiratory muscle strength, diaphragmatic function, cardiopulmonary function, and quality of life (QoL).

RESULTS

We found that IMT improved respiratory muscle strength and diaphragmatic excursion. IMT also had a beneficial effect on the incidence of postoperative pulmonary complications (PPCs) compared to CLT care.

CONCLUSION

The results from this study revealed that IMT provided positive effects on parameters associated with the respiratory muscle function and reduced the incidence of PPCs. We propose that fully engaged IMT should be a part of clinical management in patients with upper abdominal surgery.KEY MESSAGESThe fully engaged inspiratory muscle training reduces postoperative pulmonary complications rate in patients with upper abdominal surgery.The fully engaged inspiratory muscle training increases maximal inspiratory pressure in patients with upper abdominal surgery.The fully engaged inspiratory muscle training increases diaphragm function in patients with upper abdominal surgery.The fully engaged inspiratory muscle training increases the quality of life in patients with upper abdominal surgery.

Effects of breathing reeducation on cervical and pulmonary outcomes in patients with non specific chronic neck pain: A double blind randomized controlled trial

Objective

The purpose of this randomized controlled trial was to study effects of breathing reeducation in the treatment of patients with non specific chronic neck pain.

Methods

A total of sixty eight eligible patients with chronic neck pain were randomly allocated to breathing reeducation (BR) group (n = 34) and routine physical therapy (RPT) group (n = 34). Clinical outcomes were neck pain measured through visual analogue score, cervical active range of motion through CROM device, strength of neck muscles through hand held dynamometer and endurance of neck muscles measured through craniocervical flexion test. The neck disability was measured through neck disability index (NDI) and pulmonary outcomes such as forced vital capacity (FVC), forced expiratory volume in one second (FEV1), and FEV1/FVC ratio were measured through Spirolab 4. The outcomes were assessed at baseline and at 4 and at 8 weeks from baseline.

Results

There were significant improvements in the BR group compared with the RPT group (P = 0.002) for cervical flexion, extension (P = 0.029), endurance (P = 0.042), strength of neck flexors (P <0.001), neck extensors (P = 0.034). Likewise there was a significant change in NDI (P = 0.011), FEV1 (P = 0.045), FVC (P <0.001), and FEV1/FVC ratio (P <0.001) in the BR group compared with the RPT group. The cervical side flexion and rotation showed no significant difference in breathing reeducation group with p > 0.05.

Conclusion

Breathing reeducation combined with routine physical therapy is an effective treatment in patients with non specific chronic neck pain.

A Cross-Sectional Study on the Application of IS in Perioperative Pulmonary Function Training in Spine and Orthopedics

Background

The incentive spirometer (IS) is a mechanical device that promotes lung expansion and can be used to prevent and treat postoperative pulmonary complications. In this study, the preventive effect of pulmonary function training with IS on the improvement of pulmonary function and pulmonary complications was observed.

Methods

From May 2019 to April 2021, 69 scoliosis patients with impaired moderate and severe lung function were divided into the traditional pulmonary training group (n = 32) and IS-enhanced pulmonary training group (n = 35). The patient underwent lung function testing after admission and one week after the start of training and chest CT on the third day after surgery.

Results

The average age was 13.47 and 15.66, respectively (p = 0.223). The Cobb angles were 83.84 and 83.97 (p = 0.756), respectively, and no statistical difference between the parameters of lung function was detected. After 1 week of respiratory function training, significant improvement in lung function testing parameters including VC%, FVC%, FEV1%, FEV1/FVC, FEV1/VC, and MVV% was found in both groups. Analysis of covariance showed more significant improvement in IS-enhanced group compared to the conventional training group (p < 0.05). The incidence of postoperative pulmonary atelectasis was lower in IS-enhanced group than in traditional groups (2.9% vs. 21.9%, p = 0.043) with no difference in the overall incidence of pulmonary complications (p = 0.164) and shorter preoperative and total hospitalization in the IS-enhanced group.

Conclusion

Compared to traditional pulmonary function training, IS-enhanced training can significantly accelerate the improvement of pulmonary function testing parameters, shorten the preoperative pulmonary function training time, reduce the incidence of postoperative pulmonary tension complications, and accelerate postoperative rehabilitation.

The Effects of Manual Lung Hyperinflation on Pulmonary Function after Weaning from Mechanical Ventilation among Patients with Abdominal Surgeries: Randomized Clinical Trial

Introduction: After abdominal surgery, the patients who are separated from mechanical ventilation and provided with oxygen therapy via a T-piece are at risk for respiratory complications. Therefore, they need additional respiratory support. This study aimed to evaluate the effects of manual hyperinflation (MHI) on pulmonary function after weaning. Methods: This randomized clinical trial included 40 patients who had undergone abdominal surgery and were receiving oxygen via a T-piece. Patients were selected from the intensive care units (ICU) of two hospitals in Mashhad, Iran. The subjects were randomly allocated to intervention (MHI) and control groups. Patients in the MHI group were provided with three 20-minute MHI rounds using the Mapleson C, while the control group received routine cares. Tidal volume (Vt), Rapid Shallow Breathing Index (RSBI), and the ratio of arterial oxygen partial pressure to fractional inspired oxygen (P/F ratio) were measured before the intervention, as well as 5 and 20 minutes after the intervention. Atelectasis prevalence was assessed before and 24 hours after the intervention. Data were analysed by SPSS software version 13. Results: At baseline, there were no significant differences between the groups regarding Vt, RSBI, P/F ratio, and atelectasis rate. No significant difference was also found between the groups regarding atelectasis rate 24 hours after the intervention. However, at both posttests, Vt, RSBI, and P/F ratio in the MHI group were significantly better than the control group. Conclusion: In patients with artificial airway and spontaneous breathing, MHI improves pulmonary function.

The Effect of Balloon-Blowing Exercise on Postoperative Pulmonary Functions in Patients Undergoing Total Hip Arthroplasty

General anesthesia, prolonged immobilization, and pain may adversely affect pulmonary function in patients undergoing prosthetic surgery. The aim of this study was to evaluate the effect of balloon-blowing exercises on pulmonary functions in patients undergoing total hip arthroplasty. The patients in the experimental group performed three sets of balloon-blowing exercises in the morning, at noon, and in the evening on the first to third days postoperatively. The increase in forced vital capacity (FVC) values between the control and experimental groups in the postoperative period was statistically significant (p < .001), in favor of the experimental group. The increase in forced expiratory volume during the first second (FEV1)/FVC ratio was found to be significantly higher in the experimental group than in the control group (p < .001). Patients who performed balloon-blowing exercises increased their FVC and FEV1/FVC ratio.

Contrasting effects of three breathing techniques on pulmonary function, functional capacity and daily life functional tasks in patients following valve replacement surgery- A pilot randomized clinical trial

Background

Valve replacement surgeries affect the physiological mechanisms of patients leading to various postoperative pulmonary complications. Lung expansion therapy consisting of numerous techniques is routinely used for the prevention and treatment of these complications.

Objectives

Our study aimed to compare the effects of diaphragmatic breathing (DB), flow (FS) and volume-oriented incentive spirometer (VS) in patients following valve replacement surgery.

Methods

29 patients posted valve replacement surgeries were randomly assigned to VS, FS and DB groups. Patients underwent preoperative training and seven-day rehabilitation post-surgery. Pulmonary function tests were performed before surgery and for seven days afterward. On the seventh postoperative day, patients performed a six-minute walk test and completed a functional difficulties questionnaire (FDQ).

Results

Pulmonary function test values reduced in all three groups postoperatively when compared to the preoperative values but improved by the seventh postoperative day (p < 0.05). On comparing the seventh postoperative day values to the preoperative values, the VS group had no significant difference (p = 1.00) (Forced Vital Capacity- % change: DB-37.76, VS-1.59, FS-27.98), indicating that the value had nearly returned to the baseline. As compared to the DB and FS groups, FVC showed a greater improvement in the VS group (p = 0.01 and p = 0.06 respectively). No significant differences were observed between groups for distance walked (p > 0.05), however, FDQ scores demonstrated positive changes in favor of VS when contrasted with FS or DB (p < 0.05).

Conclusion

Diaphragmatic breathing, flow or volume-oriented spirometer could improve pulmonary function in the postoperative period. The volume-oriented spirometer, however, was found to be the most beneficial among the three techniques in improving patients’ pulmonary function and daily life functional tasks. Further research is warranted to confirm these findings.

•

The present pilot randomized clinical trial is the first of a kind that exhibits the effects of three breathing exercises in patients following valve replacement cardiac surgery.

•

The study demonstrates the individual and contrasting effects of volume spirometry, volume spirometry and deep breathing exercise between preoperative day until postoperative day 7 in terms of pulmonary function and function activities.

The effect of low flow anesthesia on hemodynamic and peripheral oxygenation parameters in obesity surgery

Objectives:

To investigate the effects of low-flow anesthesia on hemodynamic parameters and recovery from anesthesia in obese individuals undergoing laparoscopic surgery.

Methods:

This randomized-controlled and prospective study included 44 obese patients who underwent laparoscopic sleeve gastrectomy operation. The patients were randomly allocated into 2 groups as low-flow and high-flow anesthesia. Further, the groups compared in terms of hemodynamic parameters, anesthesia recovery times, operation times, and arterial blood gas parameters.

Results:

The groups were similar with respect to demographic data. Heart rate, peripheral oxygen saturation, arterial blood pressure measurements, end-tidal, and CO₂, lactate levels measurements were similar in both groups during the entire procedure. There was also no statistically significant difference in terms of arterial blood gas parameters or anesthesia recovery periods.

Conclusion:

Low-flow anesthesia in laparoscopic obesity surgery seems to be safer compared to high-flow anesthesia in terms of the adequacy of tissue perfusion, depth of anesthesia, and postoperative recovery.

The global impact of Coronavirus Disease 2019 (COVID-19) is tremendous on human life, not only affecting the physical and mental health of population but also impacting the economic system of countries and individual itself. The present situation demands prompt response toward COVID-19 by equipping the humans with strategies to overcome the infection and stress associated with it. These strategies must not only be limited to preventive and therapeutic measures, but also aim at improving immunity and mental health. This can be achieved by yogic breathing techniques. In this perspective, we emphasize the importance of yogic breathing, Simha Kriya and Isha kriya, the simple yet effective breathing techniques.

Effects of three pulmonary ventilation regimes in patients undergoing coronary artery bypass graft surgery: a randomized clinical trial

The aim was to compare the effect of diaphragmatic breathing exercise (DBE), flow- (FIS) and volume-oriented incentive spirometry (VIS) on pulmonary function- (PFT), functional capacity-6-Minute Walk Test (6 MWT) and Functional Difficulties Questionnaire (FDQ) in subjects undergoing Coronary Artery Bypass Graft surgery (CABG). The purpose of incorporating pulmonary ventilator regimes is to improve ventilation and avoid post-operative pulmonary complications. CABG patients (n = 72) were allocated to FIS, VIS and DBE groups (n = 24 each) by block randomization. Preoperative and postoperative values for PFT were taken until day 7 for all three groups. On 7th postoperative day, 6 MWT and FDQ was analyzed using ANOVA and post-hoc analysis. PFT values were found to be decreased on postoperative day 1(Forced Vital Capacity (FVC) = FIS group-65%, VIS group-47%, DBE group-68%) compared to preoperative day (p < 0.001). PFT values for all 3 groups recovered until postoperative day 7 (FVC = FIS group-67%, VIS group-95%, DBE group-59%) but was found to reach the baseline in VIS group (p < 0.001). When compared between 3 groups, statistically significant improvement was observed in VIS group (p < 0.001) in 6 MWT and FDQ assessment. In conclusion, VIS was proven to be more beneficial in improving the pulmonary function (FVC), functional capacity and FDQ when compared to FIS and DBE.

Incentive spirometry to prevent pulmonary complications after chest trauma: a retrospective observational study

Aim

Pulmonary complications (PCs) are a major cause of poor prognosis in chest trauma. Evidence on the effectiveness of incentive spirometry (IS) in trauma is scarce. This study investigated the effectiveness of IS in preventing PCs in patients with chest trauma with rib fractures.

Methods

This retrospective observational study analyzed the data obtained from the electronic medical records of patients with chest trauma with rib fractures admitted between 2011 and 2019. We included patients 18 years of age or older with risk of worsening respiratory failure. Early IS was the primary exposure and PCs (pulmonary infection or respiratory failure requiring escalating oxygen therapy) were the primary outcomes. Secondary outcomes were length of hospital stay, duration of oxygenation therapy, and adverse events of IS. Logistic regression analysis with a propensity score was used.

Results

We extracted 514 patients from the electronic medical records; 299 patients were included. The early IS group had a higher proportion of hypoxemia at admission, opioid analgesia use, invasive positive pressure ventilation, and respiratory physiotherapy. The severity of trauma was higher in the early IS group. There was no significant difference in the occurrence of the PCs between groups (adjusted odds ratio 0.71; 95% confidence interval, 0.24–2.16). No statistical differences were seen in the secondary outcomes.

Conclusion

For patients with chest trauma with rib fractures at risk of worsening respiratory failure, IS early after injury did not reduce the rate of PCs. No adverse event of IS was observed and IS was shown to be safe.

Comparison of Diaphragmatic Breathing Exercises, Volume, and Flow-Oriented Incentive Spirometry on Respiratory Function in Stroke Subjects: A Non-randomized Study

Abstract.

BACKGROUND

Reduced respiratory muscle strength leads to reduced pulmonary function, chest wall movements in the affected side, and increased chest infections, which thereby reduces oxygenation and ventilation. Respiratory muscle training can be used in acute stroke subjects to increase their pulmonary function.

PURPOSE

To compare the short-term effects of diaphragmatic breathing exercise, flow, and volume-oriented incentive spirometry on respiratory function following stroke.

METHODS

A non-randomized hospital-based study was conducted at Kasturba Medical College Hospitals, Mangalore, India. Forty-two sub-acute subjects of either gender, with the first episode of stroke within six months, were assigned to three groups by the consultant, i.e., diaphragmatic breathing group (DBE), Flow oriented-incentive spirometry group (FIS), and volume oriented-incentive spirometry group (VIS; N = 14) each. All subjects received intervention thrice daily, along with conventional stroke rehabilitation protocols throughout the study period. Pre- and post-intervention values were taken on alternate days until day 5 for all the three groups.

RESULTS

The pulmonary function and maximal respiratory pressures were found to be significantly increased by the end of intervention in all three groups, but FIS and DBE groups had better results than VIS (FVC = FIS group, 13.71%; VIS group, 14.89%; DBE group, 21.27%, FEV1 = FIS group, 25.97%; VIS group, 22.52%; DBE group, 19.38%, PEFR = FIS group, 38.76%; VIS group,9.75%; DBE group, 33.16%, MIP = FIS group, 28.23%; VIS group, 19.36%; DBE group, 52.14%, MEP = FIS group, 43.00%; VIS group, 22.80%; DBE group, 28.68%).

CONCLUSION

Even though all interventions had positive outcomes in all variables, flow incentive spirometry had better results across all outcomes (pulmonary function and maximal respiratory pressures) when compared to the other two interventions making it a valuable tool for stroke rehabilitation.

A randomized-controlled trial of sugammadex versus neostigmine: impact on early postoperative strength

BACKGROUND

Residual neuromuscular blockade after surgery is associated with airway obstruction, hypoxia, and respiratory complications. Compared with neostigmine, sugammadex reverses neuromuscular blockade to a train-of-four ratio > 0.9 more rapidly. It is unknown, however, whether the superior reversal profile of sugammadex improves clinically relevant measures of strength in the early postoperative period.

METHODS

Patients undergoing general, gynecological, or urologic surgery were randomized to receive either neostigmine (70 µg·kg^-1, maximum 5 mg) or sugammadex (2 or 4 mg·kg^-1) to reverse neuromuscular blockade. The primary outcome was the ability to breathe deeply measured by incentive spirometry at 30, 60, and 120 min after reversal.

RESULTS

We randomized 62 patients to either a neostigmine (n = 31) or sugammadex (n = 31) group. The incentive spirometry volume recovery trajectory was not different between the two groups (P = 0.35). Median spirometry volumes at baseline, 30, 60, and 120 min postoperatively were 2650 vs 2500 mL, 1775 vs 1750 mL, 1375 vs 2000 mL, and 1800 vs 1950 mL for the sugammadex and neostigmine groups, respectively. Postoperative incentive spirometry decrease from baseline was not different between the two groups. Hand grip strength, the ability to sit unaided, train-of-four ratio on postanesthesia care unit (PACU) admission, time to extubation, time to PACU discharge readiness, and Quality of Recovery-15 scores were also not different between the groups.

CONCLUSIONS

Measures of postoperative strength, such as incentive spirometry, hand group strength, and the ability to sit up in the early postoperative period were not different in patients who received neostigmine or sugammadex for the reversal of neuromuscular blockade.

Using an incentive spirometer reduces pulmonary complications in patients with traumatic rib fractures: a randomized controlled trial

Background

An incentive spirometer (IS) is a mechanical device that promotes lung expansion. It is commonly used to prevent postoperative lung atelectasis and decrease pulmonary complications after cardiac, lung, or abdominal surgery. This study explored its effect on lung function and pulmonary complication rates in patients with rib fractures.

Methods

Between June 2014 and May 2017, 50 adult patients with traumatic rib fractures were prospectively investigated. Patients who were unconscious, had a history of chronic obstructive pulmonary disease or asthma, or an Injury Severity Score (ISS) ≥ 16 were excluded. Patients were randomly divided into a study group (n = 24), who underwent IS therapy, and a control group (n = 26). All patients received the same analgesic protocol. Chest X-rays and pulmonary function tests (PFTs) were performed on the 5th and 7th days after trauma.

Results

The groups were considered demographically homogeneous. The mean age was 55.2 years and 68% were male. Mean pretreatment ISSs and mean number of ribs fractured were not significantly different (8.23 vs. 8.08 and 4 vs. 4, respectively). Of 50 patients, 28 (56%) developed pulmonary complications, which were more prevalent in the control group (80.7% vs. 29.2%; p = 0.001). Altogether, 25 patients had delayed hemothorax, which was more prevalent in the control group (69.2% vs. 29.2%; p = 0.005). Two patients in the control group developed atelectasis, one patient developed pneumothorax, and five patients required thoracostomy. PFT results showed decreased forced vital capacity (FVC) and forced expiratory volume in 1 s (FEV₁) in the control group. Comparing pre- and posttreatment FVC and FEV₁, the study group had significantly greater improvements (p < 0.001).

Conclusions

In conclusion, the use of an IS reduced pulmonary complications and improved PFT results in patients with rib fractures. The IS is a cost-effective device for patients with rib fractures and its use has clinical benefits without harmful effects.

Atelectasis in Bariatric Surgery: Review Analysis and Key Practical Recommendations

Obesity is a condition that affects multiple organ systems, particularly the cardiovascular and respiratory system. In recent years, bariatric surgery has been reported to be the gold standard in the treatment of morbid obesity. Body mass index alone is insufficient to predict risks related to anaesthesia and surgery. Obesity contributes to significant postoperative atelectasis and is considered an independent risk factor for postoperative atelectasis owing to decreased functional residual capacity. The treatment and reversibility of atelectasis developed in obese patients undergoing bariatric surgery are challenging. Therefore, an optimisation of pulmonary functions before surgery, lung-sparing ventilation during the perioperative period, awareness of potential postoperative complications and knowledge about preventive measures and therapeutic approaches have become increasingly important in bariatric surgery. The aim of this review was to aid clinicians in the management of atelectasis in patients undergoing bariatric surgery during the perioperative and postoperative period.

Role and impact of multimodal prehabilitation for gynecologic oncology patients in an Enhanced Recovery After Surgery (ERAS) program

Patients undergoing major surgery are predisposed to a decrease in functional capacity as a response to surgical stress that can delay post-operative recovery. A prehabilitation program consists of patient preparation strategies before surgery, and include pre-operative measures to improve functional capacity and enhance post-operative recovery. Multimodal prehabilitation may include exercise, nutritional counseling, psychological support, and optimization of underlying medical conditions, as well as cessation of unfavorable health behaviors such as smoking and drinking. Currently, there are no standardized guidelines for prehabilitation, and the existent studies are heterogeneous; however, multimodal approaches are likely to have a greater impact on functional outcomes than single management programs. We have reviewed the literature on prehabilitation in general, and in gynecologic surgery in particular, to identify tools to establish an optimal prehabilitation program within an Enhanced Recovery After Surgery (ERAS) protocol for gynecologic oncology patients. We suggest a safe, reproducible, functional, and easy-to-apply multimodal prehabilitation program for gynecologic oncology practice based on patient-tailored pre-operative medical optimization, physical training, nutritional counseling, and psychological support. The analysis of the prehabilitation program implementation in an ERAS protocol should undergo further research in order to test the efficacy on surgical outcome and recovery after surgery.

Changes of diaphragmatic excursion and lung compliance during major laparoscopic pelvic surgery: A prospective observational study

Major laparoscopic pelvic surgery requires steep Trendelenburg position with pneumoperitoneum for a long time. We investigated the effect of Trendelenburg position with pneumoperitoneum on diaphragmatic excursion and lung compliance during major laparoscopic pelvic surgery using M-mode sonography. Twenty patients undergoing elective pelviscopic radical hysterectomy were included in this study. Diaphragmatic excursion was measured at the following time points; after sedation, after intubation, 90 minutes after Trendelenburg position with pneumoperitoneum, and after operation with recovery of muscle relaxation. And lung compliance was measured using anesthetic machine under general anesthesia; after the intubation, 90 minutes after Trendelenburg position with pneumoperitoneum and after operation with recovery of muscle relaxation. In order to detect postoperative pulmonary complication, postoperative chest radiography was checked. Static lung compliance, dynamic lung compliance and diaphragmatic excursion were decreased during operation (P < 0.001, respectively). At the end of the operation with recovery of muscle relaxation, reduced diaphragmatic movement was not recovered as its excursion after sedation (P < 0.001). In conclusion, lung compliance was decreased following transiently decreased diaphragmatic excursion during major laparoscopic pelvic surgery.

The Effect of Exaggerated Lithotomy Position on Shoulder Pain after Laparoscopic Cholecystectomy

BACKGROUND

The exaggerated lithotomy position with the expertise of nurses can be successful solution for the patients who have the postoperative shoulder pain after laparoscopic cholecystectomy.

AIMS

This study aimed to determine the effect of applying an exaggerated lithotomy positions to patients who had laparoscopic cholecystectomy to relieve shoulder pain. The study was conducted on nonrandomized groups and made as a semiexperimental study with a pretest/post-test control group design. Design, Settings, and Subjects/Participants: The study was conducted on 102 patients who had elective laparoscopic cholecystectomy and agreed to participate in this study after they met the inclusion-exclusion criteria in the general surgery clinic of a training and research hospital in Istanbul between December 12, 2012, and June 30, 2013.

METHODS

The pain levels (10 minutes before and after positioning) and peripheral oxygen saturation (SPO₂) levels (1 minute, 5 minutes, and 10 minutes before and after positioning-total 6 times) of the patients were measured using a visual analog scale and pulse oximetry, respectively. The pain levels and the analgesic (pethidine hydrochloride and diclofenac sodium) usage of the patients in both the experimental and the control group were compared.

RESULTS

The exaggerated lithotomy position appreciably lowered the shoulder pain of the patients in the experimental group (t = 12.663; p = .000 < .001). It also increased peripheral saturation levels of the patients more rapidly compared with those in the control group receiving analgesics (t = 17.693; p = .000 < .005). In addition, it decreased the need to use additional analgesics and opioids (t = 2.14; p = .037).

CONCLUSIONS

In this study the exaggerated lithotomy position was found to be fast and effective for relieving shoulder pain after laparoscopic cholecystectomy, decreased the need to use additional analgesics and opioids, and, in conjunction with pain control, also contributed to improvements in respiratory functions.

Use of thoracic ultrasound by physiotherapists: a scoping review of the literature

BACKGROUND

Use of diagnostic thoracic ultrasound (TUS) in medical professions to examine the pleura, lung parenchyma and diaphragm is gaining in popularity, however the ways in which physiotherapists are using TUS is unclear.

OBJECTIVE

The aim of this scoping review is to gain an understanding of the emerging evidence base surrounding physiotherapy use of TUS to inform research and clinical practice.

DATA SOURCES

A systematic search was conducted of the following databases: Cochrane, EPPI centre, PROSPERO, Medline, CINAHL, AMED, EMBASE, HMIC, and BNI.

STUDY SELECTION

Inclusion criteria: primary research reporting the use of diagnostic TUS; a physiotherapist as part of the study design or as the chief investigator; published in English.

SYNTHESIS METHODS

Data regarding demographics, design, type of conditions and anatomical structures investigated and profession leading the TUS of included papers were compiled in a tabular format.

RESULTS

Of the 26 included papers, nine studied healthy participants, four studied COPD and four studied critical care patients. Most papers (n=23) involved scanning the diaphragm. In eight studies the physiotherapist operated the TUS.

LIMITATIONS

The paper selection process was performed by one author; with no cross-checking by another individual.

CONCLUSION

Use of TUS by physiotherapists is an emerging area in both diaphragm and lung diagnostics. A wide range of patient populations may benefit from physiotherapists using TUS. Papers in this review are heterogeneous making any generalisability difficult but does show its potential for varied uses. TUS is an innovative skill in the hands of physiotherapists, but more research is needed.
