1. Introduction

Acute ischemic stroke (AIS) continues to represent one of the greatest public health challenges worldwide due to its high incidence, elevated mortality, and substantial burden of long-term disability. As the predominant subtype of stroke, accounting for nearly 85% of all cases, AIS results from the abrupt interruption of cerebral perfusion, initiating a cascade of metabolic, inflammatory, and cellular events that culminate in irreversible neuronal injury. The extent of neurological impairment is largely determined by the balance between the irreversibly damaged infarct core and the surrounding ischemic penumbra, whose preservation remains the principal therapeutic target in modern stroke management (CAMPBELL; KHATRI, 2020) [12]; (POWERS et al., 2019) [54]. The management of AIS has evolved considerably over the past two decades, largely driven by advances in reperfusion therapy. Intravenous thrombolysis with alteplase continues to be recommended for eligible patients presenting within the established therapeutic window, while mechanical thrombectomy has emerged as the preferred treatment for acute large vessel occlusion. The combination of these strategies has transformed the prognosis of selected patients by increasing recanalization rates and reducing permanent neurological disability (POWERS et al., 2019) [54]; (BERGE et al., 2021) [5]. Clinical evidence further demonstrates that shorter times from symptom onset to reperfusion are consistently associated with better functional outcomes and lower long-term dependence (EMBERSON et al., 2014) [21]; (SAVER et al., 2015) [61].

The incorporation of mechanical thrombectomy into routine clinical practice was supported by landmark randomized controlled trials that consistently demonstrated its superiority over conventional medical therapy. Studies including MR CLEAN, ESCAPE, EXTEND-IA, SWIFT PRIME, and REVASCAT established endovascular thrombectomy as a highly effective intervention for appropriately selected patients with proximal intracranial occlusions (BERKHEMER et al., 2015) [6]; (CAMPBELL et al., 2015) [15]; (GOYAL et al., 2015) [24]; (SAVER et al., 2015) [61]; (JOVIN et al., 2015) [30]. Subsequent investigations, particularly the DAWN and DEFUSE-3 trials, expanded patient eligibility by demonstrating the safety and efficacy of thrombectomy beyond the traditional therapeutic window when guided by advanced imaging techniques (NOGUEIRA et al., 2018) [50]; (ALBERS et al., 2018) [1]. Despite these therapeutic advances, successful arterial recanalization does not invariably translate into complete neurological recovery. Many patients continue to experience substantial functional impairment despite technically successful reperfusion, reflecting the complex pathophysiology of ischemia-reperfusion injury, microvascular dysfunction, cerebral edema, inflammatory activation, and delayed neuronal death. These observations indicate that restoring cerebral blood flow alone is insufficient to fully prevent secondary brain injury (CHAMORRO; DIRNAGL; URRA; PLANAS, 2016) [17]; (SAVITZ et al., 2017) [59].

Consequently, increasing attention has been directed toward neuroprotective interventions designed to preserve neuronal viability throughout the acute phase of ischemic stroke. Rather than replacing reperfusion therapies, neuroprotection aims to complement them by minimizing secondary cellular damage and extending tissue survival during and after reperfusion. Current neuroprotective strategies emphasize meticulous physiological management, including optimization of blood pressure, glucose control, oxygenation, temperature regulation, and prevention of systemic complications, while numerous pharmacological approaches continue to be investigated for their potential to attenuate ischemic injury (POWERS et al., 2019) [54]; (DAMMAVALAM; AGHAEBRAHIM; RAI, 2024) [19]. Nevertheless, although experimental studies have yielded encouraging findings, translating these interventions into consistent clinical benefit remains an ongoing challenge (DIRNAGL; ENDRES, 2014) [20]; (NEUHAUS et al., 2017) [48]. The widespread implementation of mechanical thrombectomy has renewed interest in combining reperfusion therapies with adjunctive neuroprotective measures. Rapid restoration of cerebral circulation creates a favorable therapeutic environment in which pharmacological and non-pharmacological interventions may further protect the ischemic penumbra and reduce reperfusion-related injury. Recent investigations have explored optimized hemodynamic management, targeted neurocritical care, and novel neuroprotective agents as complementary strategies capable of improving outcomes following successful thrombectomy (HILL et al., 2020) [28]; (WANG et al., 2026) [68]. These developments support the incorporation of neuroprotection into standardized hospital stroke pathways. Modern stroke care extends far beyond emergency reperfusion procedures. Contemporary hospital protocols encompass a coordinated continuum of care beginning with rapid diagnosis and extending through intensive monitoring, complication prevention, early mobilization, and structured rehabilitation. Specialized Stroke Units have consistently demonstrated superior clinical outcomes compared with conventional hospital care, including lower mortality rates, fewer medical complications, shorter hospital stays, and greater functional independence after discharge (STROKE UNIT TRIALISTS' COLLABORATION, 2013) [62]; (POWERS et al., 2019) [54].

Within these organized systems of care, multidisciplinary collaboration has become indispensable. Neurologists, emergency physicians, interventional neuroradiologists, nurses, physiotherapists, occupational therapists, speech-language pathologists, and other healthcare professionals contribute complementary expertise throughout every phase of patient management. Effective communication among these disciplines facilitates timely reperfusion, continuous neurological monitoring, prevention of secondary complications, and individualized rehabilitation planning, ultimately enhancing neurological recovery and quality of life (WINSTEIN et al., 2016) [70]; (MINELLI et al., 2022) [42]. Among the professionals involved in stroke care, physiotherapists play a central role from the earliest stages of hospitalization. Their interventions include respiratory support, prevention of immobilization-related complications, maintenance of musculoskeletal function, progressive mobilization, balance training, and stimulation of neuroplastic mechanisms that promote functional recovery. Evidence indicates that initiating rehabilitation during the acute hospital phase contributes to improved motor performance, reduced disability, shorter hospitalization, and greater independence in activities of daily living (LANGHORNE; BERNHARDT; KWAKKEL, 2011) [32]; (POLLOCK et al., 2014) [52]; (VEERBEEK et al., 2014) [67]. Timely intervention remains one of the strongest determinants of prognosis in AIS. The well-established concept that "time is brain" reflects the rapid and continuous loss of viable neurons that accompanies untreated cerebral ischemia. Delays in symptom recognition, emergency transport, neuroimaging, or reperfusion treatment significantly reduce the likelihood of favorable neurological recovery, underscoring the importance of efficient in-hospital workflows and integrated stroke systems capable of minimizing treatment delays (SAVER, 2006) [60]; (MERETOJA et al., 2014) [41]; (RIBO et al., 2016) [56]. Given the continuous expansion of scientific evidence concerning mechanical thrombectomy, neuroprotective interventions, and multidisciplinary rehabilitation, a comprehensive synthesis of current knowledge is warranted. Therefore, this systematic review was conducted to critically evaluate the available evidence regarding evidence-based hospital protocols for acute ischemic stroke, with particular emphasis on the integration of neuroprotective strategies, mechanical thrombectomy, and multidisciplinary rehabilitation as essential components of contemporary stroke care.

The studies included in this systematic review demonstrate that physical therapy plays a fundamental role in all phases of the acute ischemic stroke hospital protocol (Table 2). Physiotherapeutic interventions commence upon admission to the Stroke Unit, encompassing early functional assessment, respiratory monitoring, safe mobilization, and the prevention of complications secondary to immobility. It was observed that early mobilization, when performed in an individualized and clinically safe manner, is associated with shorter hospital stays, improved functionality, and greater independence in activities of daily living. Additionally, respiratory physiotherapy techniques helped mitigate pulmonary complications, whereas motor, balance, and gait training programs enhanced neuroplasticity and functional outcomes. Altogether, these findings highlight the necessity of active physiotherapist involvement in specialized multidisciplinary stroke teams, proving vital to the neurological and functional recovery of patients following mechanical thrombectomy.

Evidence from the analyzed studies confirms that nursing is central to the acute ischemic stroke hospital protocol, performing tasks ranging from initial symptom recognition to discharge planning. Primary responsibilities involve 'Stroke Code' activation, serial monitoring of neurological and hemodynamic status, safe pharmacological administration, and prophylaxis of complications related to hospitalization (Table 3).

The literature demonstrates that clinical surveillance by the nursing team contributes directly to the early detection of neurological deterioration, rigorous control of physiological factors associated with neuroprotection, and a reduction in adverse events. Furthermore, health education and the coordination of multidisciplinary care have proven fundamental in ensuring therapeutic continuity, treatment adherence, and improved functional outcomes following hospital discharge.

Consequently, nursing is established as a cornerstone of modern stroke protocols, actively participating in reperfusion, neuroprotection, and rehabilitation strategies.

4.1. Introduction to the Acute Ischemic Stroke Hospital

Care Protocol Acute ischemic stroke (AIS) represents a major neurological emergency in clinical practice, accounting for substantial rates of mortality, functional disability, and socioeconomic burden worldwide. The rapid interruption of cerebral blood flow triggers a cascade of pathophysiological events that can lead to irreversible neuronal death in the absence of early therapeutic intervention. In this context, the implementation of standardized hospital protocols has become one of the most effective strategies to reduce diagnostic delays, optimize clinical decision-making, and improve outcomes for patients affected by this condition (Powers et al., 2019) [54]; (Campbell & Khatri, 2020) [12].

Over the last few decades, significant advances have occurred in the treatment of acute ischemic stroke, particularly with the consolidation of intravenous thrombolysis and mechanical thrombectomy as reperfusion therapies capable of restoring cerebral blood flow and salvaging the ischemic penumbra. However, the success of these interventions relies directly on the speed and efficiency of hospital care, reinforcing the need for well-structured clinical protocols that are integrated across different healthcare disciplines (Berkhemer et al., 2015) [6]; (Goyal et al., 2015) [24]; (Nogueira et al., 2018) [50]. Beyond reperfusion therapies, the adoption of neuroprotective measures constitutes an essential component of modern stroke management. Strategies such as rigorous blood pressure control, maintenance of normoglycemia, prevention of hyperthermia, adequate oxygenation, and continuous neurological monitoring contribute to minimizing secondary brain injury and maximizing the benefits derived from vascular recanalization. Consequently, neuroprotection has come to be considered a complementary and indispensable phase within contemporary acute ischemic stroke management protocols (Chamorro et al., 2016) [17]; (Savitz et al., 2017) [59]; (Dammavalam, Aghaebrahim, & Rai, 2024) [19].

Stroke patient care also requires a multidisciplinary approach, involving physicians, nurses, physical therapists, speech-language pathologists, occupational therapists, and other specialized professionals. The integration of these teams enables not only clinical stabilization and acute treatment but also early initiation of rehabilitation, a factor associated with a reduction in complications, shorter hospital stays, and improved long-term functional outcomes (Winstein et al., 2016) [70]; (Minelli et al., 2022) [42]. Given this scenario, the development of a standardized hospital protocol aims to systematically organize all stages of care, from early symptom identification and 'Stroke Code' activation to cerebral reperfusion, intensive monitoring, neuroprotection, and multidisciplinary rehabilitation. The implementation of these evidence-based measures contributes significantly to improving the quality of care, reducing mortality, and maximizing the functional recovery of patients affected by acute ischemic stroke."

5. Discussion

The results of this systematic review demonstrate that the implementation of structured hospital protocols for acute ischemic stroke care is directly associated with reduced mortality, decreased functional disability, and improved clinical outcomes. The consolidation of intravenous thrombolysis and, notably, mechanical thrombectomy has transformed stroke management over the last two decades, enabling previously unattainable rates of cerebral reperfusion and significantly expanding the possibilities for neurological recovery (POWERS et al., 2019) [54]; (TURC et al., 2019) [65]. The studies analyzed demonstrate that mechanical thrombectomy is currently the standard of care for patients with large intracranial vessel occlusion. Clinical trials such as MR CLEAN, ESCAPE, SWIFT PRIME, EXTEND-IA, and REVASCAT have shown consistent benefits in functional independence and reduced disability at three-month follow-up, consolidating the superiority of the endovascular approach compared to clinical treatment alone (BERKHEMER et al., 2015) [6]; (CAMPBELL et al., 2015) [15]; (GOYAL et al., 2015) [24]; (SAVER et al., 2015) [61]; (JOVIN et al., 2015) [30]. Furthermore, the DAWN and DEFUSE-3 trials have extended the therapeutic window for cases selected via advanced neuroimaging, allowing a greater number of patients to benefit from mechanical reperfusion (NOGUEIRA et al., 2018) [50]; (ALBERS et al., 2018) [1]. However, despite the advances observed in vascular recanalization, several studies have indicated that successful reperfusion does not always result in satisfactory neurological recovery. This finding reinforces the importance of secondary injury resulting from processes of excitotoxicity, neuroinflammation, oxidative stress, and ischemia-reperfusion injury, mechanisms that remain active even after the restoration of cerebral blood flow (CHAMORRO et al., 2016) [17]; (SAVITZ et al., 2017) [59]. In this context, neuroprotective strategies emerge as complementary tools capable of enhancing the benefits of mechanical thrombectomy and preserving brain areas that remain viable.

The literature analyzed demonstrated that clinical measures considered neuroprotective are already part of the routine in modern stroke protocols. Rigorous control of blood pressure, blood glucose, body temperature, and oxygenation has been associated with reduced cerebral infarct expansion and improved functional outcomes (POWERS et al., 2019) [54]; (YANG et al., 2022) [71]. Although several pharmacological agents have been investigated over the years, clinical results still remain limited when compared to the benefits observed in experimental models. Recent studies suggest that the combination of neuroprotective therapies and early reperfusion may represent one of the primary areas for future development in the treatment of acute ischemic stroke (HILL et al., 2020) [28]; (WANG et al., 2026) [68]. Another relevant aspect identified in this review was the importance of organizational structure through Stroke Units. Data showed that patients treated in specialized centers exhibit lower mortality, fewer hospital complications, and a higher probability of functional recovery compared to those treated in conventional units (STROKE UNIT TRIALISTS’ COLLABORATION, 2013) [62]. These results reinforce that therapeutic success depends not only on available technology but also on the efficiency of care workflows and the integration among involved professionals. Nursing stands out as a fundamental element for the success of hospital protocols. Rapid symptom identification, Stroke Code activation, continuous monitoring of neurological and hemodynamic parameters, and the prevention of hospital-related complications have proven to be determinant for the safety and effectiveness of the treatment. The continuous involvement of the nursing team allows for the early detection of neurological deterioration and contributes directly to the implementation of neuroprotective measures recommended by international guidelines (WINSTEIN et al., 2016) [70]; (ROYAL COLLEGE OF PHYSICIANS, 2023) [57]. Likewise, physical therapy plays an indispensable role throughout the entire care process. Studies have shown that early mobilization, progressive motor training, respiratory management, and the prevention of complications associated with immobility significantly contribute to patients' functional recovery. Furthermore, the early stimulation of cerebral neuroplasticity promotes neural reorganization and maximizes the gains achieved through reperfusion therapies (LANGHORNE; BERNHARDT; KWAKKEL, 2011) [32]; (POLLOCK et al., 2014) [52]; (VEERBEEK et al., 2014) [67]. The concept of multidisciplinary care has also been widely consolidated in the literature. Integration among neurologists, intensivists, nurses, physical therapists, speech-language pathologists, occupational therapists, and other professionals allows for a more comprehensive approach to patient needs, favoring both neurological recovery and social and functional reintegration after hospital discharge (WINSTEIN et al., 2016) [70]; (MINELLI et al., 2022) [42]. Finally, the results reinforce that time remains one of the primary prognostic determinants in acute ischemic stroke. The concept of "time is brain" remains current, demonstrating that delays at any stage of care significantly reduce the benefits of cerebral reperfusion and increase the likelihood of permanent disability (SAVER, 2006) [60]; (MERETOJA et al., 2014) [41]; (RIBO et al., 2016) [56]. Thus, efficient hospital protocols, combined with neuroprotective strategies and early rehabilitation, constitute the fundamental pillars for optimizing clinical outcomes in acute ischemic stroke Final Considerations This systematic review demonstrated that mechanical thrombectomy represents one of the most significant evolutions in the treatment of acute ischemic stroke, providing high rates of cerebral reperfusion and better functional outcomes when performed early and in appropriately selected patients. However, optimal neurological recovery does not depend exclusively on vascular recanalization; it is strongly influenced by the implementation of neuroprotective strategies and the quality of multidisciplinary care provided throughout the entire hospital stay.

The evidence analyzed indicates that neuroprotective measures based on hemodynamic, metabolic, and respiratory control play a fundamental role in preserving the ischemic penumbra and reducing secondary brain damage. Furthermore, the integrated performance of medical, nursing, and physical therapy teams has proven essential for preventing complications, ensuring continuous clinical monitoring, and facilitating the early initiation of functional rehabilitation.

The results also reinforce the importance of Stroke Units and standardized hospital protocols as tools capable of reducing the time to reperfusion, improving care safety, and increasing the chances of functional independence after a cerebrovascular event. In this context, the integration of rapid diagnosis, mechanical thrombectomy, neuroprotection, and multidisciplinary rehabilitation must be considered an indispensable component of modern stroke care systems. Finally, it is observed that further research is necessary to deepen the understanding of specific neuroprotective therapies associated with mechanical thrombectomy, particularly regarding their clinical efficacy, applicability across different populations, and impact on long-term outcomes. The consolidation of these strategies could contribute significantly to the refinement of hospital protocols and to the reduction of the global burden of acute ischemic stroke.
