Effects of ankle pump exercise frequency on venous hemodynamics of the lower limb

The impact of ankle movements on venous return flow: A comparative study

OBJECTIVE

To compare the haemodynamic effects of different ankle movements combined ankle and toe movements on the femoral vein of the lower extremity.

METHODS

28 healthy volunteers participated in the study. Doppler ultrasound was used to measure peak systolic velocity and time-averaged mean velocity of the common femoral vein during ankle dorsiflexion, ankle dorsiflexion with simultaneous toe extension, ankle plantarflexion, and ankle plantarflexion with simultaneous toe flexion.

RESULTS

In comparison to the resting state, both ankle alone or ankle combined with toe movement showed statistically significant differences (p < .01). However, there were no significant difference in the velocity of the common femoral vein between ankle alone and ankle combined with toe movement (p > .05). It is noteworthy that dorsiflexion of the ankle resulted in the highest peak velocity of blood flow.

CONCLUSION

The impact of ankle movement, with or without toe movement, the velocity of the common femoral vein is not significantly correlated.

The effect of physical therapy and mechanical stimulation on dysfunction of lower extremities after total pelvic exenteration in cervical carcinoma patient with rectovesicovaginal fistula induced by radiotherapy: a case report

BACKGROUND

Total pelvic exenteration is the ultimate solution for rectovesicovaginal fistula caused by radiation therapy, yet total pelvic exenteration frequently causes intraoperative complications and postoperative complications. These complications are responsible for the dysfunction of lower extremities, impaired quality of life, and even the high long-term morbidity rate, thus multidisciplinary cooperation and early intervention for prevention of complications are necessary. Physical therapy was found to reduce the postoperative complications and promote rehabilitation, yet the effect on how physiotherapy prevents and treats complications after total pelvic exenteration and pelvic lymphadenectomy remains unclear.

CASE PRESENTATION

A 50-year-old Chinese woman gradually developed perianal and pelvic floor pain and discomfort, right lower limb numbness, and involuntary vaginal discharge owing to recurrence and metastasis of cervical cancer more than half a year ago. Diagnosed as rectovesicovaginal fistula caused by radiation, she received total pelvic exenteration and subsequently developed severe lower limb edema, swelling pain, obturator nerve injury, and motor dysfunction. The patient was referred to a physiotherapist who performed rehabilitation evaluation and found edema in both lower extremities, right inguinal region pain (numeric pain rate scale 5/10), decreased temperature sensation and light touch in the medial thigh of the right lower limb, decreased right hip adductor muscle strength (manual muscle test 1/5) and right hip flexor muscle strength (manual muscle test 1/5), inability actively to adduct and flex the right hip with knee extension, low de Morton mobility Index score (0/100), and low Modified Barthel Index score (35/100). Routine physiotherapy was performed in 2 weeks, including therapeutic exercises, mechanical stimulation and electrical stimulation as well as manual therapy. The outcomes showed that physiotherapy significantly reduced lower limb pain and swelling, and improved hip range of motion, motor function, and activities of daily living, but still did not prevent thrombosis.

CONCLUSION

Standardized physical therapy demonstrates the effect on postoperative complications after total pelvic exenteration and pelvic lymphadenectomy. This supports the necessity of multidisciplinary cooperation and early physiotherapy intervention. Further research is needed to determine the causes of thrombosis after standardized intervention, and more randomized controlled trials are needed to investigate the efficacy of physical therapy after total pelvic exenteration.

The effect of the Ankle Pump Exercise (APE) counter system assisted ankle pump motion in patients after femoral neck fracture

OBJECTIVE

To explore the effect of the Ankle Pump Exercise (APE) counter system on moderate to high-risk Venous thromboembolism (VTE) after femoral neck fracture surgery.

METHODS

From June 2021 to June 2022, a total of 140 patients with moderate and high-risk VTE after femoral neck fracture surgery treated at the Department of Orthopedics of a tertiary hospital in Zhejiang were included and divided into observation (70 cases) and control (70 cases) groups according to whether APE counter system was used or not. The control group was given routine oral propaganda, and the observation group was given a comprehensive nursing intervention with APE counter system on the basis of the control group's treatment. The compliance rates of the two groups on the postoperative 3st, 5rd, and 7th days were compared. Moreover, the General self-efficacy scale (GSES) was used to evaluate self-efficacy before and after exercise.

RESULTS

The compliance rates of the control group and the observation group on the postoperative 3st, 5rd, and 7th days were 74.3% vs. 85.7%, 67.1% vs. 85.7%, and 61.4% vs. 82.9%. On the 5rd and 7th days, the compliance of the observation group was obviously higher than that of the control group. Moreover, the mean postoperative GSES score was also significantly higher than that in the control group (23.20 ± 3.516 vs. 25.31 ± 4.583, P < 0.05, values are expressed in mean ± standard).

CONCLUSION

APE counter system can significantly improve the compliance and self-efficacy of patients with moderate and high-risk VTE after lower limb fracture surgery.

Nursing diagnosis proposal "Impaired Peripheral Venous Return": concept formation

OBJECTIVES

to develop a nursing diagnosis proposal focused on venous return.

METHODS

this is a concept analysis according to the model proposed by Walker and Avant, which is operationalized through an integrative review. The study was carried out according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses protocol recommendations.

RESULTS

the analysis of the 131 studies allowed identifying attributes, antecedents and consequences. The most common attribute was decreased venous flow. The antecedents most frequently found were structural and/or functional valve deficiency, advanced age and peripheral venous thrombosis. The most common consequences were peripheral edema, venous ulcer and pain in the extremity.

CONCLUSIONS

the formulated nursing diagnosis was proposed as part of Domain 4, Activity/rest, in Class 4, Cardiovascular/pulmonary responses, with eight defining characteristics, five related factors, six at-risk populations and four associated conditions.

Early Mobilization, Early Ambulation, and Burn Therapy in the Acute Hospital Setting

Rehabilitation therapies in the burn acute care environment continue to evolve. Immediate access to therapy is considered standard, and therapy is a key component of the transprofessional care team. Early positioning, edema management, and therapy care in the intensive care unit (ICU) environment can limit later complications; mobility in the ICU can be engaged safely using a systems-based approach in the absence of nondirectable agitation. Later in the course of acute care, early ambulation is an appropriate intervention that can improve outcomes.

Evaluation of a New Method of Sciatic Nerve Block: A Prospective Pilot Study

Purpose

The location of the sciatic nerve deep within the thigh tissue makes it challenging to locate while the patient is in a supine position. The posterior intermuscular septum of the thigh, which encircles the posterior surface of the adductor magnus muscle (AMM), is where the sciatic nerve is located. Our hypothesis was that administering local anesthetic injections into this area could block the sciatic nerve. Therefore, our aim was to evaluate the effectiveness of sciatic nerve block achieved by injecting local anesthetic into the posterior intermuscular septum of the thigh, named the AMM approach.

Methods

Twenty-six patients undergoing total knee arthroplasty were included in the study. We performed an ultrasound-guided sciatic nerve block by injecting 20 mL of 0.25% ropivacaine into the posterior surface of the adductor magnus muscle, using the AMM approach. Additionally, we administered a femoral nerve block with 20 mL of 0.4% ropivacaine. We assessed the sensory and motor effects of the blockade in the operated lower limb and recorded postoperative pain scores at 0, 4, 8, 12, 24, and 48 hours after the operation.

Results

The AMM approach successfully block the sciatic nerve in all 26 patients. The onset of the sensory and motor blockades was achieved within 5.4 ± 1.9 min and 8.7 ± 3.5 min, respectively. We achieved a satisfactory position with the first puncture in 19 of 26 patients (73.1%). The muscle strength of the tibialis anterior immediately after surgery was 4 (ranging from 2 to 5). Additional rescue analgesics were required in 5 of the 26 patients (19.2%) during the first 24 hours postoperatively.

Conclusion

The AMM approach is an innovative and effective method for sciatic nerve block. When combined with simultaneous femoral nerve block in patients undergoing total knee arthroplasty, it provides a useful analgesic treatment option.

Views of inpatients on the prevention of venous thrombosis with ankle pump exercise: A cross-sectional survey

INTRODUCTION

This study investigated the current status of patients' knowledge and clinical compliance with ankle pump exercises in order to better enhance patient education and improve patient compliance with ankle pump exercises.

METHODS

A cross-sectional survey of the current status of ankle pump exercise awareness and compliance was conducted using a self-designed questionnaire. The questionnaire consisted of a general demographic information questionnaire, a questionnaire on patients' perceptions of ankle pump exercise and a compliance questionnaire.

RESULTS

A total of 2,203 patients from 53 clinical departments participated in this survey. 87.8% of patients considered ankle pump exercise important, 92.1% could grasp the knowledge of ankle pump exercise, 48.5% could self-monitor and exercise daily as instructed, 81.5% of health care workers would often supervise patients to complete ankle pump exercise, poor self-control (34.6%), lack of physical strength (21.1%) and perceived hassle (18.9%) were the top 3 factors contributing to patients' inability to complete the ankle pump exercise. Regression analysis showed that the factors influencing patients' compliance with the ankle pump exercise were literacy, economic level, number of comorbidities and caprini risk class (p < .05).

CONCLUSION

The patient's cognition of ankle pump exercise is good, but the compliance needs to be improved. It is suggested that the compliance of ankle pump exercise in hospitalized patients should be improved in the future to reduce the incidence of Venous thromboembolism.

Which Frequency of Ankle Pump Exercise Should Be Chosen for the Prophylaxis of Deep Vein Thrombosis?

Introduction

Ankle pump exercise (APE) is an effective method to prevent deep vein thrombosis (DVT) in the lower extremities. However, traditional APE at a frequency of 3 times/min applied in the clinic lacked high compliance, and individuals were found to prefer an APE of 30 times/min. This study aimed to compare the effects of APEs with the above two different frequencies on the venous hemodynamics and fatigue of lower extremities.

Methods

The study applied a randomized cross-over design, and 307 healthy adults were randomly assigned into two groups, whose left feet performed 5 minutes of traditional APE (3 times/min, after 10 minutes of rest) and 5 minutes of selected APE (30 times/min, after 10 minutes of rest) in different orders. The diameters and blood flow velocities of the external iliac vein, femoral vein, and popliteal vein of the left extremities were recorded with the color doppler ultrasound when participants were at rest and after 5 minutes of traditional or selected APE. The fatigue of lower extremities was assessed with the Rating of Perceived Exertion (RPE) after the participants performed 5 minutes of different APEs.

Results

After both traditional APE and selected APE, the diameters and blood flow (peak systolic) velocities of the external iliac vein, femoral vein, and popliteal vein increased significantly in the participants (P<.01), and the effects of the two APEs on venous hemodynamics of the lower extremities had no significant difference (P>.05). However, participants reported that traditional APE caused higher fatigue, and 252 (82.1%) participants preferred APE at 30 times/min.

Conclusion

Both traditional and selected APE could increase venous blood flow in the lower extremity. Despite the equivalent effects, the selected APE of 30 times/min may cause less fatigue than the traditional one of 3 times/min.
